This was the result of me moving about directories under du's feet. I
wouldn't really have minded if it had just bombed out with the ENOENT
message (after all, I think it's allowed to fail if I mess it around),
but the coredump suggests an actual bug.
Note that although you see the word `ubuntu' in the filename, and
indeed the directory /slash/ubuntu is an ubuntu chroot, the overall
system is a Debian one, so this is Debian's su. The system is more or
less running sarge with a few packages from early post-sarge testing.

Also, here is my transcript of what I was doing in the other window
that made du break. I can't tell from here when the coredump
happened, I'm afraid:
