TypeError: int() argument must be a string or a number

Expected results:

obsSense should either always be list or an int - it may be an
rpm-python bug if so reassign and I'll look into.

Additional info:

I think this may be an rpm-python bug as you are doing 
obsflags[index] in genObsoleteTupleFromHeader.  I'll try and investigate.
