Langsam dämmert mir, dass ich wohl schon vorher ein Problem hatte.
Ich hatte nun versucht mailman über aptitude wieder zu deinstallieren, da kommen dann auch diese Fehler mit "ImportError: No module named message" u.a.

Ich hatte den gar nicht installiert, ein Kollege tat das.
Vermutlich war die Installation schon fehlerhaft.

Deinstallieren kann ich aber auch nicht.
In Aptitude ist mailman mit C markiert, also halb konfiguriert. 
Will ich mailman löschen erhalte ich einen ähnlichen Fehlerhagel:
