Christopher, thanks for posting your Xorg.0.log. The stack trace there is quite different from the original crash. Since the patch on the upstream bug report is already deployed and the bug set as fixed, there's not much point reopening it, which means this bug report is stale. Let's close it out and have you open a new bug report.
Please file a new bug report after reproducing the crash via this command:
