Description of problem:

On two of my up2date Fedora 7 machines some repoquery command stopped working:

# sudo repoquery --repoid=fedora -a --archlist 'noarch'
Loading "fastestmirror" plugin
Loading mirror speeds from cached hostfile
fedora                    100% |=========================| 2.1 kB    00:00

Version-Release number of selected component (if applicable):
$ rpm -q yum yum-utils
yum-3.2.2-1.fc7
yum-utils-1.1.6-1.fc7

How reproducible:
Always

Steps to Reproduce:
1. sudo repoquery --repoid=fedora -a
-> works fine
2. sudo repoquery --repoid=fedora -a --archlist 'noarch'
-> fails (see above)
3. sudo repoquery --repoid=fedora-source -a --archlist="src
-> fails in a similar way
  
Additional info:
I noticed I got new yum and yum-utils package over the last few days on both the
machine where the error happens. The same commands that fail work fine on
another machine that still has yum-3.2.1-1.fc7 and yum-utils-1.1.5-1.fc7

All three testmachines are x86_64 (in case it matters).
