Comment 3 for bug 629527

Between the master bug (this one) and the duplicates, date/clock and login name all seem capable of overwriting the shutdown icon. I can confirm this bug, it happens sometimes and I couldn't find a way to reproduce the bug. It just happens. But I found a work-around: every time it happens I press "Alt + F2", write "xkill" and hit "Run". The pointer is now going to be an "X". You only have to put the pointer over the Task Bar and left-click your mouse. You can also 'restart/log out' your computer, but it takes more time.
