Hello.

I've got a fresh ubuntu lucid lynx installation with all updates from yesterday, 2010-03-29. When I install banshee everything works perfectly fine until I install the mirage extension. Then banshee comes up with a fatal error message saying:
An unhandled exception was thrown: Object reference not set to an instance of an object
