Damnit. Very sorry for the noise, but I just noticed that it IS NOT
related to the clones. It crashes with the clone/promote lines
(#77-78) commented out, too...
Now I'm stumped as to where the issue is, I hope the previous mail can
help track it down.
A very similar setup runs every night, and it "only" crashes about one
time in 10 or so. This crashes *every* time and I don't really see the
difference between the commands the scripts run. Oh well...
