Bug Description
Binary package hint: compiz
After losing side & top panels [result from 'guest session' switching] & filing bug [Bug #746094 ], I tried reboot to regain unity desktop [if I'm correct that its unity I want?].
I opened terminal [keyboard shortcut], typed 'unity', hit enter and apport window opened for this report.
Copy of terminal output is in attached 'TermOutput' file.
As terminal output progressed, the top & side panel returned & are presently fully functional.
