banshee starts and soon stops by itself

[Bernhard Kleine]

Banshee has been correctly running for two weeks, after that it starts and stops without any possibility to interfere.

Ubuntu 11.10, banshee 2.2.1, packages updated within the last 24 hrs.

I expect banshee to start and to let me choose audio or internet radio.

Instead of that it shuts down.

here is the banshee --debug protocol:

banshee --debug

With the recent banshee update, banshee is still not working, the debug report changed slightly, see attachment.

De-installing the banshee-extension-ubuntuonemusicstore package on a fresh Ubuntu 11.10 install got rid of the problem.
