I've been using Banshee on Ubuntu for years, and on 13.04 specifically since 13.04 was released.
I update my system regularly but can't think of anything likely to cause the error, which is:
I googled the error and found threads dating back to 2005 but none of the answers has worked for me.
Unhandled Exception: System.IO.FileNotFoundException: No such file or directory ---> Mono.Unix.UnixIOException: No such file or directory [ENOENT].
I also uninstalled and reinstalled banshee with no luck.
Any ideas what this is about?
