Since updating to ubuntu 11.10 I've had trouble with banshee. In particular when I run it I find that it crashes within an hour without fail. I get the following

     Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object

Does anyone else also have this problem?
