should we catch the KeyError in controlpanel/gui.py?

[walter]

If there is no xklavier module installed there is a KeyError in jarabe/controlpanel.py

        try:
            import xklavier
        except ImportError:
            del self._options['keyboard']

self._options doesn't always seem to have a 'keyboard' entry.

But keyboard component has been loaded anyway(despite of having xklavier), so we need to remove proper control component.
I tested it in my env(last git) with and without xklavier and didn't get error, could you reproduce this issue with last versions.

Perhaps I have a bad build. I'll do a clean install to see if the problem persists. But that key did not exist on sugar-jhbuild on Ubunutu.

The problem seems to have gone away with a clean build--because import xklavier is now successful. When I force the ImportError, I still have the problem with KeyError. I am not sure why the key is missing, but if we trap the error, then the control panel still opens. Otherwise it does not.
