@Joe, could you collect a full backtrace on this bug? I think it'd provide some better details than was captured in that log.
See http://wiki.ubuntu.com/X/Backtracing for guidance on collecting backtraces. In this case I think skip the apport bits, and use gdb directly. ** Changed in: xorg-server (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/831336 Title: running 'xterm' exists X session To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/831336/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
