 From a packaging perspective, the seem to be different.  I have both
- python-twisted-2.5.0-1mdv2008.0
- python-twisted-core-2.5.0-3mdv2008.1
However, they both seem to be v2.5.0 ...

Mail eh?  Sorry, but I never would have suspected that as the problem
from the error messages... :P

Well, I'm not sure what the version number means, but it seems that
the next version of python-twisted-mail jumps from 0.3 to 8.1!
http://fr2.rpmfind.net/linux/rpm2html/search.php?query=python-twisted-mail&submit=Search+...&system=mandriva&arch=

So, I tried backporting/installing it, and the unit tests seem to
have gotten *much* further!  There's still a couple of disconcerting
looking messages, but it's looking pretty close!

Ya, it seems that way.  Now that the problem seems to be isolated,
I'll be trying to point this out to them, to hopefully fix+prevent it
in the future.

Many thanks for all the help so far!  If I can get those last couple
of messages resolved (Or, get confirmation they can be ignored), then
I think I'll be ready to start trying to actually *use* buildbot... ;)
