[Bug 705078] Re: Xorg crashed with SIGSEGV in pixman_image_set_has_client_clip()

 

Hi, visiting from bug 708744. I managed to collect a crash report of one
of our failed systems (a Dell Vostro 3400), which I'm attaching,
hopefully it will help confirm what Bryce found. This happens during the
live install process, stopping the installation and dropping the user
into a LiveCD environment/session.

I'll also try the submitted fix on all our systems, though I can't do
that until monday.

Here's the backtrace as requested, the attached .crash file has
additional information.
