Totem did not work with upnp/dlna plugin

Binary package hint: totem

Description: Ubuntu 11.04
Release: 11.04
totem 2.32.0-0ubuntu
python-coheren 0.6.6.2-5

This functionality works pretty well on the i386 side, i use it very often on my laptops.

Install totem and phyton-coherence
Launch totem, enter plgugin menu and click X upnp/dlna plugin

Now totem goes to a freeze for around 30s, then a dialog appears: Plugin »Coherence DLNA/UPnP-Client« konnte nicht aktiviert werden
Launched from a terminal you get this:
