[Banshee-List] error on "Delete from Drive" in "File System Queue"

[wonder <gogo wonder gmail com>]

Whenever I tried to delete a file in "File System Queue", banshee just terminates. 
This is the message provided in the debug mode:

Unhandled Exception: System.InvalidCastException: Cannot cast from source type to destination type.
