 The keyboard control panel is currently broken in Debian due to some
 configuration issue. I'm still investigating the reasons for this. The
 important thing for now is that this causes Sugar to be unresponsive.
 Since the Control Panel is globally modal, there's no way short of killing
 Sugar to recover from the unresponsiveness. Simply activating the keyboard
 control panel will trigger this bug.

 Traceback on entering the keyboard control panel:

 This ticket is about the keyboard control panel not recovering from
 configuration issues. In the long run, we should make the control panel
 fullscreen and non-modal anyway; that would fix the unresponsiveness part
 as a side effect.
