Hi, I'm running svn-14882 on Debian Unstable. I recently made some
changes. I was running fairly well but i was getting some tearing
watching highdef video so I updated to the new Intel 2.2.0 driver. At
the same time I synced to the most recent svn from the version from a
vew days ago. Now when i stop watching a video, the frontend
segfaults. I've attached the info that i can think of, but let me know
if I can give more info.
Thanks,
Brad
