pessulus produces a useless debuginfo package:

$ rpm -qlp
http://fedoraproject.org/extras/development/i386/debug/pessulus-debuginfo-0.10.1-2.fc6.i386.rpm
(contains no files)

http://fedoraproject.org/wiki/Packaging/Debuginfo

I don't see any architecture dependent files in the package, so maybe it should
actually be noarch?  That would require changing it so that it doesn't install
to python_sitearch, but python_sitelib.

If the noarch change is not the right thing to do, the useless debuginfo package
can be disabled by doing a %define debug_package %{nil}
