In my experience it depends from theme. I use the UBUNTU DAWN theme with MAC ICONS and long time I haven't seen this problem, but I re-logged into a different user with the default theme and suddenly the power button was broken... With my beloved settings it has never happened so far!
For Märt Suga: Does it happen to u all the time booting like this. Try out my settings, it would be great to see, if it was a theme related problem.
