Hi. Since Ubuntu 12.04 I have an issue where I keep on crashing out my session to the logon prompt when I am playing a video file. I have reinstalled from scratch several times, all to no avail. The bug is actually listed here: https://bugs.launchpad.net/ubuntu/+s...rg/+bug/951796
but there seems to have been no resolution. Version 11.10 works fine.

Any ideas please? It's driving me nuts!
