Other information:
This happened to me using an 11.x release, so I tried to compile 12.0 from source, and it's still occurring.  I'm using Ubuntu Edgy.  

I can't figure out how to get a proper stack trace, because all my attempts at calling "$ LD_LIBRARY_PATH=/usr/lib/banshee mono --debug /usr/local/bin/banshee" result in a "cannot open assembly /usr/local/bin/banshee"

Everything worked fine for me for months until today.  Not sure if it was the result of a new mono or what.
