compiz crashed with SIGSEGV in nux::Focusable::SetFocused()

Binary package hint: unity

When i use unity i often get a message "The program compiz closed unexpectedly" and the keyboard stops working. This happened several times so i decided to report it. When it crashes, i still have icons on the desktop, then i go to the /usr/share/applications and launch the gnome panel from there so i can log out and log in to get unity working again.
