Plymouth splash screen missing; Unity menu and window decorations are missing too

[Tomé]

After the today's update of Quantal Alpha, I've noticed that the Plymouth splash screen is missing. The bug report system (apport?) informed that "plymouthd crashed with SIGSEGV in script_obj_deref_direct()"

Also, after the logint, the window decorations/Unity menu haven't been loaded.

I'm using an HP dm1-3250br (AMD E-350) with the latest "radeon" driver.

I'd be glad to help with more information if needed.
