traceback with 20021011 current snapshot

This is a 100% reproducible traceback when rebuilding my
"redhat-linux-i386-6.2" channel. It includes all of the original RH
6.2 packages and all of the errata.

FWIW, it's perfectly OK with me if Current drops RH 6.2 support -- I plan
to get the 6.2 machines under my administrative control upgraded to 7.3
anyway. Nonetheless, I thought you might want to know about this bug.

If you need any more info, feel free to ask -- as I said, this is 100%
reproducible.
