Nach dem Linux-Distro-Upgrade gibt Moin unter WSGI 500 Fehler aus

Ich habe eine MoinMoin- Instanz installiert bei /opt/mydebianwiki; Das Wiki läuft unter [wsgi] / [apache2]. Ich habe kürzlich ein Upgrade von Debian Linux 6 (Squeeze) auf Debian 7 (Wheezy) durchgeführt. Vor dem Upgrade funktionierte meine MoinMoin- Instanz gut.

Nach dem Upgrade auf Wheezy bekam ich jedoch HTTP 500-Fehler, als ich versuchte, auf die Website zuzugreifen.

Googeln führte mich zu diesem Moin-User-Thread, der besagte, dass ich einfach laufen könnte su -c "moin --config-dir=/opt/mydebianwiki maint cleancache" www-data, um das Problem zu beheben. Dies war jedoch ebenfalls nicht erfolgreich (siehe Fehler unten in der Frage).

Wie kann ich dieses Problem lösen?
