[Banshee-List] Banshee Encountered a Fatal Error

["Natalia Fisher" <puffin gmail com>]

Banshee crashed while I was doing a bunch of other stuff on my computer (unsuccessfully trying to install PhotoShop Elements through CrossOver Office).  When I next tried to run it, I got this error message and Banshee subsequently wouldn't open.

===============================================
I have since uninstalled Banshee (which I had compiled from CVS), and tried installing the version in the Ubuntu package manager and got the same error.  I tried compiling and installing 
0.10.12 and got the same error again.  The next time I deleted /usr/lib/banshee and compiled and installed the latest CVS, and still no luck. What should I do?  Is there a file (the database file?) I missed that I should have deleted?

Thanks for any help.
