could also be an issue in the new gtk

Comment 1 Sebastien Bacher 2008-08-07 09:49:31 UTC

there is no gnome-panel function there, reassigning to gtk

Comment 2 Michael Natterer 2008-08-07 10:38:27 UTC

Same crash in sizegroup happens in gimp when closing an image
(using gtk trunk as of today):

GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `GtkContainer'
aborting...

Program received signal SIGTRAP, Trace/breakpoint trap.

Comment 3 Michael Natterer 2008-08-07 13:43:02 UTC

Fixed in SVN:

2008-08-07  Michael Natterer  <mitch@imendio.com>

	Bug 546756 – gnome-panel crashed with SIGSEGV in
	g_type_check_instance_cast()

	* gtk/gtkimagemenuitem.c: add GtkObject::destroy() implementation
	and remove the image now that it's an internal child and isn't
	destroyed by gtk_container_destroy() any longer. Thanks to tml for
	helping bisecting this down.
