Comment (by nomeata):

 > You'll have to look at the code, but only locally-defined Ids have their
 rules attached. The rest are in a global database (the rule-base)

 Ah, thanks for clearing that up for me. I always assumed that the rule
 base is only for orphan rules. Now I know where to look, and will
 hopefully find out what’s wrong.
