This exact same thing occurs on my FC6 system today, and is repeatable every
time.  Same dump file, so will not include it.

[root@fc6-32 ~]# rpm -q --whatprovides /usr/sbin/pup
pirut-1.2.8-1.fc6

The process never gets to the point of displaying the updates available.

This has also just started to happen on my FC6 system as well (first ocurred
today 23rd Feb 07). Software updates were working fine until today!

Again, exact same dump file.

Not sure I understand meaning of "(most recent call last)" in traceback. Does
that mean that in the traceback shown above, the most recent call is the line
indicated by this?:
"File "/usr/lib/python2.4/site-packages/yum/yumRepo.py", line 426, in __get"

I have a traceback that looks similar at the top of the listing shown above, but
differs in the details shown below. I'm not sure if it is more helpful to add my
traceback here or create a separate defect report. For now I will add it here,
and gladly create another defect report if informed that I should. Thank you for
being patient.

Here is the content of my crashdump file:

I started getting this crash on Tuesday. Happens regardless of the packages I
select to update. Here is my crash dump:

Thank you for the report. However this has been reported to the incorrect
component. Reassigning from "up2date" to "pirut". Feel free to report any
further bugs you find to our bug tracking system.

These should be resolved with the current update versions of pirut
