PyGTK: issue packing widgets into dialog

Oct 24th, 2007

Hello all,

I've been having a ton of trouble with this custom gtk dialog I am trying to create. The code "runs" however I receive a GtkWarning message saying:

/home/maddog39/Projects/mmoalert/actiondialog.py:42: GtkWarning: gtk_box_pack_end: assertion `child->parent == NULL' failed
  self.message_hbox.pack_end(self.message_entry)

For the life of me, I can't seem to figure out what going on and why this is happening. As usual, its probably something very simple that keeps passing by me. Heres the code for the dialog.
