[PATCH] Fix TestPkgRelations failures with python3.

Hi John,

It's not clear to me what this change is fixing -- is the test suite failing 
for you under some version of python? It passes for me with python3 from 
wheezy and various versions that have been in sid and also works fine on 
ci.debian.net so I'm not quite sure what's happening here.


cheers
Stuart
