Description of problem: I clicked on the edit cluster properties and then closed it, and then clicked it again and got this assertion /usr/share/system-config-cluster/ConfigTabController.py:358: GtkWarning: file gtkcontainer.c: line 1285 (gtk_container_foreach): assertion `GTK_IS_CONTAINER (container)' failed self.cluster_props_dlg.show() Version-Release number of selected component (if applicable): system-config-cluster-0.9.33-1.0.noarch.rpm
This must have happened because the dialog 'X' button was clicked to close the window. The delete event was not being handled -- now it is in 0.9.36-1.0
fix verified in 0.9.36.
