Added some new tracks to my library tonight, and I've noticed that Banshee crashes when trying to edit the metadata of those tracks -- and it seems to affect all fields (eg title, artist etc).

I've confirmed that it affects several filetypes, including MP3 and FLAC.

Here is the stack trace from the console at the moment of the crash (This, specifically, was trying to edit the artist of an mp3):
