Yes, the setting was set to the GConf backend. I guessed that maybe that setting was broken so I set it to the flat file configuration backend (which caused unity to crash) and then back to GConf. Now everything is working fine and I've never seen this error message again. That wonders me because I'ved never changed that setting before, the setting must be damaged in another way. The bug is invalid. Thank you for your help an sorry that I've bugged you with this.
