So it's returning "None" for me as kernel_version, which means it's 
falling through all of these cases.

I used stock FC4 as the repository.  I updated a number of packages on the
system itself via yum.  I tried running against two different kernels.

Note: I did build a new kernel on this box, though I never actually ran 
it.  Could building the kernel have changed some things that Kadischi 
assumes will be present by default?

And would it help if I gave you the contents of rpm.TransactionSet 
(rootdir) when I get this error?
