That was the first thing I thought of, but the failure originally
occurred yesterday in koji, and I still can't reproduce it today in
mock.  I also looked at the root.log and didn't notice any differences
in installed package versions.  (Although it seemed that the root.log
was being generated by a slightly different python script, because the
line numbers in the left margin were different.  Should I be worried
about that?)
