sometimes unity breaks: ALT+F2 shows a broken window, icons don't work.
I have to switch to a new terminal (CTRL,ALT+F1) and try
$ setsid unity
Sometimes it works (unity restarted and everything is fine), sometimes not.
The attachment shows what I see on the screen.

This report seems to refer to several problems (broken alt+f2 window, no icons). Would be nice to have some screenshot to understand what's going on.
