This case happens in situation where u hold the alt key for a while (say 2 to 3 secs) and press the tab button, then monitor flashes implies unity breakdowns and move all the applications to single workspace, if you repeat it second time , you will end up with un accessible desktop where all applications hang with no title bars

Then you have only one option restart unity (ctrl + alt + f1) login enter "unity" command and enter (ctrl + alt f7)

U will get back your desktop but you have to arrange all the applications in the respective workspaces, which makes my day very very bad, I have switched back to linux mint which is atleast stable than this unity crap...and ubuntu 12.04 is a nightmare
