Xorg crashed with SIGSEGV in pixman_image_set_has_client_clip()

[Mario Limonciello]

Similar to bug 705078. This occurred on a different machine and later into the installation, but still during a ubiquity install.

This is almost certainly a dupe of 705078, the backtraces and log output leading up to the crash is nearly identical. Thanks for filing it separately though, as it gives us additional hw data to compare against.
