Comment 112 for bug 562027

I have the exact same problem on Ubuntu 11.10 64bit. In Gnome shell, classic, unity, and unity 2d I cannot log out, shutdown, etc. while the quicktray starter is on.
Only when I shut it off can I log out, etc.
Also, in Unity-2d (and I think gnome classic, i can't remember) an error message would come up when trying to open libreoffice from a shortcut while the quickstarter is on, that multiple processes of libreoffice are active.
