radio, then banshee crashed. I had to force quit banshee. Since then,
i'm getting fatal error same as Greg. When I entered banshee --debug in
terminal, I got

Title:
An unhandled exception was thrown: Object reference not set to an
instance of an object
Status in “banshee” package in Ubuntu:
Incomplete
Bug description:
Binary package hint: banshee
I was listening to an internet radio station when this error occurred.
The window with the exception (pasted below) popped up, then banshee
switched to a different (unfortunately annoying) internet radio
station. I couldn't stop playback nor close banshee. I copied the
exception out of the popup and tried to close the popup, no response.
Had to do a killall banshee-1.
Unfortunately apport didn't catch this.
Exception output:
An unhandled exception was thrown: Object reference not set to an
instance of an object
