Banshee.exe crashed with SIGSEGV in __strlen_sse2()

Hi,

This is the first time Banshee crashed in my computer.
When starting, it just said that there were a problem (an exception launch somewhere… I just remember of viewing a sql request with a variable IsTemporary checked if it is equal to 1). Then the window of Banshee (and the one that said there were an error with it) did not answer then. I was thus forced to kill them with xkill.
When I restarted again Banshee, apport launched and I was filling this bug repport.
I’ve then tried to re-launched Banshee again. It seems to work, it even started to play something, but it crashes as soon as I typed a song in the research entry.
When I re-launched it again, it works the first 3 seconds, but crashes afterward.

I don’t know what happens.
Hoping it will help,
Martin.
