Assertion fails on exit when signal hook is present and appears-as-list=1
Submitted by Ruslan Kabatsayev
Link to original bug (#640106)
Description
I get these errors when the window of the program attached is closed:
(test:9906): GLib-GObject-CRITICAL **: g_object_ref: assertion `object->ref_count > 0' failed
(test:9906): GLib-GObject-CRITICAL **: g_object_ref: assertion `object->ref_count > 0' failed
This is only when GtkComboBox::appears-as-list=1 is set in gtkrc.
