clicking a keyboard shortcut entry locks up the whole desktop

[Logan Rosen]

Not sure if this is a regression, as I haven't played much with shortcuts before. However, when you enter the Keyboard panel and click on a shortcut that you want to change, the whole desktop locks up until you hit the Escape key (after which everything starts working again, a couple of seconds after hitting the key).

Furthermore, clicking one of these entries yields the following error in the terminal (when gnome-control-center is invoked from there):

(gnome-control-center.real:67357): Gdk-CRITICAL **: gdk_window_get_window_type: assertion 'GDK_IS_WINDOW (window)' failed
