gtk-2 bug, inconsistency or simply misunderstanding on my side ?

Hi Owen,

The container is removed with gtk_widget_destroy. By "freed twice", I
mean that the widget destroy routine "mywidget_destroy(GtkObject
*object)" is called twice, usually leading to a core dump.

The gtkdial widget, given as example in gtk+-2.0.x source tree should be
enough to see the problem, by adding a simple trace to
gtk_dial_destroy() every time it's called.

I'll try to make a simple test case that shows this behaviour. As I
said, I might just be misunderstanding something, so I don't pretend
that anything is not legitimate in gtk :)
