gnome-control-center crashed with SIGSEGV in g_type_create_instance()

[quantenemitter]

Trying to circumvent bug #834523, I've adjusted a line in gnome-region-panel.desktop to get keyboard layout selection. This is what happened next:

$ cat /usr/share/applications/gnome-region-panel.desktop |grep Only
OnlyShowIn=GNOME;Unity;

$ gnome-control-center region
