Comment 2 for bug 380736

I don't have any problems setting "π" as a name in my metadata, nor does Banshee crash when playing the track.

Can you provide specific steps and the problems (error, crash, what you were expecting to happen) that result from them?

As for the track not changing in-disk, do you have "Write metadata to files" and "Update file and folder names" checked in Edit | Preferences (on the General tab)?
