Comment 2 for bug 139050

This error occurs on my gentoo system with dbus running as a service and all other apps using dbus without reporting any problem...
...probably an f-spot problem.

erik@0x0065 ~ $ f-spot
System.ApplicationException: F-Spot cannot find the Dbus session bus. Make sure dbus is configured properly or start a new session for f-spot using "dbus-launch f-spot" ---> System.Exception: Unable to open the session message bus. ---> System.ArgumentNullException: Argument cannot be null.
