Eeek.  OK.  Then I recommend you work around it for now.  If you want
to see how it _will_ behave when urlgrabber gets into the 1.0 series,
just grab urlgrabber from a 2.0 release and do waht I described
above.  Make sure you run python1.5, though.  It will be exactly the
same file.  It's written to work for 1.5 and 2.x (although with some
added capabilities for 2.x).

If it works, then it will probably work in a soon-to-come 1.x series
release.  If it doesn't work, then that's interesting and we should
fix it.  (this is all assuming that it's a yum issue in the first
place).
