[ubuntu-in] Shutdown restart option missing

[ramnarayan.k at gmail.com]

Hi

Am in the process of updating my 7.10 , but seem to have run into a
minor problem. In the logout/shutdown option (accessed via the icon on
the desktop bar or via the System-> Quit route) the Shutdown and restart
 options have gone missing, but the logout, suspend, hibernate or lock
screen option are there

I can shutdown or restart via the terminal.

So any idea what might be causing this ?? and what i need to do ??

thanks
ram
