Bug Description

When I change the language on lock screen with keyboard shortcut, the system freezes for a few seconds, the lock screen disappears (I haven't typed a password), for fraction of a second I see all my windows and then the lock screen appears again.

I can recreate this every time (on two clean Ubuntu installations with the latest updates), but it happens only if I change the language with a keyboard shortcut. Everything is fine if I change the language from the top menu.

After I login ubuntu-bug utility reports an issue with /usr/bin/compiz.
