I have actually come across 3 different errors now...
1]
Gtk-CRITICAL **: file  gtkcontainer.c: line 730 (gtk_container_remove): assertion
`widget->parent == GTK_WIDGET(container)' failed.
(2 of them actually, as I remove 2 widgets)
Which I take to mean that I am trying to remove some widget from it's parent when
it has already been removed...this one happens pretty randomly after clicking on
the  button a ton of times.

2]
Is a standard gnome crash box w/o any warnings...circumstances are the same as
above.

3]
2 Gtk-Critical : gtk_container_remove's (same as above) followed by:
Gtk-CRITICAL **: file gtkwidget.c line 1386 (gtk_widget_destroy): assertion
`GTK_OBJECT_CONSTRUCTED(widget)' failed.

#3 seems to be the most significant problem, and maybe all three are the same
problem, but that sometimes the crash is caught sooner or something...

I'm really pretty new to linux, and the only debugger I ever used in windows was
the one in VC6, and the one I wrote as part of a z80 emulator for the TI-86
calculator...

I'll see if I can whip up a nice little gtk app that has this problem...shouldnt
take more than like 15 minutes at the most.
