Shutdown cog disappears

[RobinJ]

I'm running Ubuntu 11.10 (daily builds) with all the latest updates on my desktop.
After running for a few minutes (sometimes half an hour even) the shutdown cog at the top right corner of the screen disappears. I've been experiencing this since I first tried the daily builds (around alpha 2), and I thought it'd be fixed by now, so I decided to report it as all the other bug reports I've found about this say it has been fixed already.
All the other indicators just stay there, only the shutdown cog disappears.
I don't really know what other information would be usefull for solving this bug, but if you need any more data, just ask.

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