Nautilus global menu not visible (Ubuntu Precise + Quantal)

[Andreas]

The Global menu for Nautilus appears, but is unavailable.

What I expect to happen: When I click on it, the menu should appear.
What happens instead: a small rectangle appears under the menu item, but I cannot access anything (screenshot attached)

This only happens from time to time, usually after the system has been up and running for a couple days. Rebooting always fixes the issue.

I have been experiencing this with Precise and Quantal 64bit.

nautilus -q fixes this problem. Don't know if it comes back or not. Will leave system running.

thank you for your bug report, is the issue limited to nautilus? could be an unity/appmenu issue as well...

This only happens with nautilus.
