Comment 55 for bug 250506

Hm, I just tried to shut down and it worked flawlessly. (it rarely does, usually something hangs in the init scripts)
The important part: The menu item worked as well. Don't know why it did now and didn't some other times, but I will try to observe that further and post a session list here when it goes wrong again. I am sure it didn't work after the fix was posted here sometimes.
