Public bug reported:

When entering Unity, screen blinks and go back to lightdm.

For now I found this:
[  795.921152] show_signal_msg: 21 callbacks suppressed
[  795.921157] compiz[1535]: segfault at d72 ip 00007f9b827c7390 sp 00007fff01bc9e50 error 4 in r600_dri.so[7f9b82793000+c7000]

I'm using Unity2D for now and I need to know how to backtrace compiz.
