[ubuntu-mono] [Bug 877016] [NEW] Banshee freezes on startup, multiple cpus at 100%

Tue Oct 18 01:45:05 UTC 2011

Public bug reported:

The Banshee application freezes just seconds after application startup,
putting all four(!) of my laptop's cpus at 95% usage.

The only way to shut down the application is to 'Force Quit'.

I ran banshee from the command line with 'banshee --debug' and have
attached the complete application logs.  The logs contain the following
two exception tracebacks at the end:

** (Banshee:8620): WARNING **: Error calling get_info: Traceback (most recent call last):
