Summary:                    xfdesktop crashes on load after first time a session was saved
Description: 
after having saved a session on logout, everytime i start xfce, xfdesktop
quitd with the following error message:
The program 'xfdesktop' received an X Window System error.
The error was 'BadAtom (invalid Atom Parameter)'.
(Details: serial 228 error_code 5 request_code 20 minor_code 0)

if i delete my .xfce directory, it works again, until i save the session
on logout...
interesting: even after the error occured, i can start xfdesktop manually
and it behaves as expected.
does anybody have an idea about why this happens?
