Docky fail to start

Installed docky first from official Repo, then from universe. Both times same error.
"Vorgegebener Überwachungstyp für lokale Ordner konnte nicht gefunden werden" is german and means as much as "Default monitor type for local folders could not be found".

Using ubuntu 12.10 64bit
