I have downgraded to Ubuntu 10.04.2 LTS for stability and I just installed Banshee through the software center. I don't have any Banshee plugins installed. When I try to open Banshee I just get this error:

An unhandled exception was thrown: Could not read add-in description

Here is the terminal output. Immediately after this, a dialog box pops up giving me the same error as I pasted above.

I have no idea why it's doing this. "Could not read add-in description." If it's referring to third-party extensions, then once again, I don't have any installed. Any help would be appreciated.

I solved this problem by deleting the directory ~/.config/banshee-1/addin-db-001. It works just fine now.
