Sure, that it is really protectbase letting it fail in the end? I think the 
problem occurs because of the way protectbase works. It just excludes x 
packages and it checks against that list. Nothing else. I don't think that 
it is consulted again at that stage. Real protection would be to check with 
each package before installation which package it replaces and then check 
if the to-be-replaced package is from a protected repo or not (which is 
done by matching of the name and not by looking it up in a local database - 
the better way would be to store the repo in a database when a package gets 
installed - this way you would always know where it came from.)
