Re: [gtkmm] I've got a lot of segfaults in combination with Dialogs

[Bart Hakvoort <bart hakvoort castel nl>]

I think i've localized the problem, the segfaults only appear when i've
added widgets to the "widgetarea". When i've done this and execute the
program, i'll get the following warning every time i close the dialog. (
its no error! only a warning in the terminal from where i started the
application )

(dialogtest:21152): Gtk-CRITICAL **: file gtkcontainer.c: line 878
(gtk_container_remove): assertion `GTK_IS_CONTAINER (container)' failed

I'll get this warning for every widget i've attached to the Dialog, so
in the source example i've included in this message it happens two times
( a label and a entry ) each time you close the dialog.

When i close the dialog ( it doesn't matter if you use OK or CANCEL )
the segfault occurs. sometimes the first time, sometimes the 10th, but
it *will* segfault.

As i've built all mij Dialogs this way i hope someone knows how to solve
this, so i can fix my application.
