Logout/Suspend/Shutdown button goes missing in 13.10

[Dac Chartrand]

The Gear Icon goes missing, at random. This has happened ~3 times since I upgraded to 13.10. I must reboot to get the button back. See attached screenshot

Expected: Gear icon in the upper right, where one can find several options including Logout/Suspend/Shutdown

Actual: No button.

Thank you for your consideration.

Uhhh, sorry, I don't think this bug belongs in 'light-themes'. I am using Ambiance (Default) - Although switching themes when the problem occurs (Radiance, High Contrast) does nothing IE the icon remains missing until reboot.

Can someone please triage correctly? Thanks.

Optionally, instead of rebooting I can reset Unity doing:

  dconf reset -f /org/compiz/
  setsid unity

This (also) brings back the missing Gear Icon, but I'm not sure if this is overkill.

Status changed to 'Confirmed' because the bug affects multiple users.

 It appeared when i upgraded from raring to saucy though. But the icon is missing in a clean 13.10 install.
