compiz.real crashed with SIGSEGV

Binary package hint: compiz

Try to sign in, in gnome. Black screen for a lot of time. Just mouse arrow is visible. Some time later a visible popup windows was show comunicating a crash detect.
So, I had install kubuntu-desktop, to get a X client,
and submit this crash report with:
 apport-cli -c /var/crash/_usr_bin_compiz.real.1000.crash
