QGIS » QGIS Application

After an upgrade of qgis in ubuntu 13.04 qgis does not start normal.
At first there is the message:

"[Fehler] Kann private Kopie von qgis.db nicht anlegen" 

Then is there an python error:

Konnte Erweiterung processing nicht laden wegen eines Fehler beim Aufruf seiner classFactory()-Methode
