I've been running a 6.0 from Friday for a week now without seeing this panic, so I suspect it's fixed. However, I don't remember seeing any commits which look like they were responsible for fixing it, is it possible that it's just been masked by some other commit? I'm happy to step back and find the responsible commit, unless you're happy that it was fixed for certain. Gavin
