I am having a problem with unity. I have launched Movie player with QNapi (application for downloading movie subtitles) and somehow Unity crashed and disappeared leaving just the opened windows without the launchers, title bars and unity's top bar.

enter image description here

After I go to Ctrl + Alt + F1 and try to unity --reset I get this error

Segmentation fault (core dumped)
WARNING: Unity currently default profile, so switching to metacity while resetting the values

What can I do (besides reboot) ?

EDIT

Launching Unity Panel from compiz didn't help either.
