PY2EXE Compilation: Obscure Vista Issue

[Raygoe]

Well, for the first time it seems I have stumbled onto a bug I have never been able to figure out with google.

Application Type:
wxPython 2.8.9.1 (Python 2.6 Version ANSI)
Python 2.6
py2exe 0.6.9

Anyways,
I compiled an application that uses wxPython. I then proceeded to run the application where after it draws the dialog it crashes.

I proceeded to try and see what the errors were. In my research I came across something interesting. It only crashed when I placed my mouse over the dialog.

Moreover, I did more studying...

If I compiled it with windows or console option both times it crashed the same way.

I then ported it to my XP in which it ran successfully.

That XP system did not have Python 2.6.

To check I ported it to another XP system with Python 2.5 on it. It also ran successfully.

To counter the Vista check I ran it on my other Vista system and it also failed. It did not have Python.

On all systems I have installed the MSVC++ 2008 Redistributable.

The specific error vista returns in the dialog is:

Attached is everything from the source, the DLLs used, the build data and the distributed executable. (Basically, everything)

Edit: Attachment wouldn't work... 7mb is evidently too big to handle. I uploaded it onto my website: http://www.auburnflame.com/error.zip

Anyways, if you need more information or have a solution please go ahead and post!

Oh by the way,
I don't believe it is a permissions problem as I ran it as Administrator both times on vista and not and it didn't work either way.
Running it with XP computability mode failed as well.

Thanks for your help!

Ok, does any other wxpy program run successful? I ask because may be version is wrong (I always prefer unicode). Another problem is installing wxpy with less admin rights. Try to re-install wxpy in Admin level. Try same code but compile with 2.5

[Raygoe]

I just tried compiling a different program and it did not crash.

I will try compiling under 2.5 and see if that makes any difference.

[Raygoe]

Oh, this is interesting...

I just tried running the main.py in the source through python and it crashes the same way as the py2exe does.

I guess that means it isn't py2exe that is the problem...

[Raygoe]

I've narrowed down the problem to this:

This works when python.exe runs it:

import wx

class MyMenu(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, wx.DefaultPosition, wx.Size(200, 150))

        
	menubar = wx.MenuBar()
        file = wx.Menu()
        edit = wx.Menu()
        help = wx.Menu()
        file.Append(101, '&Open', 'Open a new document')
        file.Append(102, '&Save', 'Save the document')
        file.AppendSeparator()
        quit = wx.MenuItem(file, 105, '&Quit\tCtrl+Q', 'Quit the Application')
        #quit.SetBitmap(wx.Image('stock_exit-16.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap())
        file.AppendItem(quit)

        menubar.Append(file, '&File')
        menubar.Append(edit, '&Edit')
        menubar.Append(help, '&Help')
        self.SetMenuBar(menubar)
        self.CreateStatusBar()
		

class MyApp(wx.App):
    def OnInit(self):
        frame = MyMenu(None, -1, 'menu1.py')
        frame.Show(True)
        return True

app = MyApp(0)
app.MainLoop()

This doesn't:

import wx

class MyMenu(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, wx.DefaultPosition, wx.Size(200, 150))

        """
	menubar = wx.MenuBar()
        file = wx.Menu()
        edit = wx.Menu()
        help = wx.Menu()
        file.Append(101, '&Open', 'Open a new document')
        file.Append(102, '&Save', 'Save the document')
        file.AppendSeparator()
        quit = wx.MenuItem(file, 105, '&Quit\tCtrl+Q', 'Quit the Application')
        #quit.SetBitmap(wx.Image('stock_exit-16.png', wx.BITMAP_TYPE_PNG).ConvertToBitmap())
        file.AppendItem(quit)

        menubar.Append(file, '&File')
        menubar.Append(edit, '&Edit')
        menubar.Append(help, '&Help')
        self.SetMenuBar(menubar)
        self.CreateStatusBar()
		"""

class MyApp(wx.App):
    def OnInit(self):
        frame = MyMenu(None, -1, 'menu1.py')
        frame.Show(True)
        return True

app = MyApp(0)
app.MainLoop()

Basically, adding just a
self.CreateStatusBar() keeps it from crashing... strange errors!

[jbennet]

Hmm yeah i just whipped up a test program and managed to recreate the same issue on server 2008

must be some bug in NT6

[Raygoe]

Confirmed.

I added a self.CreateStatusBar() to the code on the main.py and it worked like a charm.

Why? What's the significance of that?

Thanks for the info bennet!

Just to be thorough: does that work for everyone? If so, I'd love to mark solved but I really want to know why that works...

[jbennet]

I was using the 64 bit version of windows server 08 (vista sp1 based). Are you using the 32 or 64 bit version of vista? service pack level?

this guy here has the same issue on 64 bit vista
http://trac.wxwidgets.org/ticket/10082

this guy here has a similar (but not identical) issue in vista 32 bit and python 2.6
http://trac.wxwidgets.org/ticket/10122

maybe python 2.5 doesnt have the bug?

[Raygoe]

All of my testing was done on 32 bit systems. Both Vistas were SP1

[jbennet]

hmm yeah it must be an issue which affects all vista-based systems, which is annoying

you should submit a bug report
