f-spot chrashes on start

[Sebastian]

when I start f-spot it crashes. A window is shown shortly, then closed, nothing happens

From a terminal it looks like this:

sebastian@gauss:~$ f-spot
Starting new FSpot server

Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object
in <0x00171> PhotoStore:Query (System.String query)
in <0x0044a> PhotoStore:Query (.Tag[] tags, .DateRange range)
in <0x00025> FSpot.PhotoQuery:.ctor (.PhotoStore store)

in <0x0002a> FSpot.Core:get_MainWindow ()
in <0x0000c> FSpot.Core:Organize ()
in <0x004d8> FSpot.Driver:Main (System.String[] args)

Thats all ...
