[Bug 30293] logout user menu entry tooltip is incorrect

[Daniel Robitaille]

Public bug reported:
https://launchpad.net/malone/bugs/30293

Affects: gnome-panel (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
If I move my mouse cursor over the Log Out option in the System menu
entry, the tooltip says "Log out Daniel Robitaille of this session to
log in as a different user or to shut down your computer".

But this is incorrect since the recent reorganization of these logout
menu entries  and the shut down option is not available anymore via this
logout menu entry but via its own "Shut Down" entry.
