I tried to "completely remove" all of the cupsys-packages, and later re-install them.
Unfortunately without any achievements.
Since I use my laptop for work as well, and since it's harddrive has very limited space, I have been forced to downgrade to Dapper. I hope that this bug was somehow related to misconfigurations on my machine, I haven't seen many bug-reports concerning these issues anyway.

But thanks for the help.
