All tested mozilla apps (firefox, thunderbird and seamonkey) freeze on startup
with nouveau-dri-10.2.1 libraries. If nouveau-dri libraries downgraded to
10.1.4, freezes gone, even without restarting x-server.
Freeze localized in forked mozilla process (with ~100% cpu eating), killing
this process can be restore mozilla's startup.
This bug detected only in nouveau dual-screen configuration. Intel dual-screen
works nornally, nouveau single-screen works too.
