H3C confirmed and fixed a bug with this exact issue in their switch software. Apparently the bitstrings in Q-BRIDGE-MIB::dot1qVlanStaticTable columns were reversed.
Updating the software on our H3C switch reveals a slight typo in the above fix, which has been fixed here: http://metanav.uninett.no/hg/series/3.9.x/rev/5a04a8dee552
With the updated H3C software (5.20 Feature 2210L04) and these patches, the issue seems to be resolved.
