[CentOS] Crash during yum update

Hello all:

I was getting a reproducible crash during an update of a xen system.
The problem went away after I set SELinux to permissive, but the fact
that it crashed was alarming (first one on a non-dev system that I've
had in over a year).  I attempted the update earlier but it crashed at
the same point after attempting to update selinux.  After verifying
hardware (all clean) I ran it again and crashed in the same location.
Third time failed again in same location. I rebooted, changed selinux,
then it completed after that. Unfortunately there are no dumps and I
had to put the system back into operation. Didn't see anything in
bugzilla either. Anyone else seen this?


Here's the console output:
