GTK Warnings when closing MGD (Ubuntu only)

Occasionally on closing the application the system will show errors from the GIMP Toolkit (GTK) similar to the following:

LIBDBUSMENU-GTK-CRITICAL **: watch_submenu: assertion `GTK_IS_MENU_SHELL(menu)' failed
(Mali Graphics Debugger:3989): LIBDBUSMENU-GLIB-WARNING **: Trying to remove a child that
doesn't believe we're it's parent.

These are believed to relate to issues within GTK itself: they are widely reported and are believed to be harmless.
