I once was bitten by this, too:

   The "meta type" field in the type information must be that of
   the instances created by the constructor. I.e., you must
   not modify the field unless you use a different constructor
   which puts the modified "meta_type" into the instances.

   Otherwise, the instances will not be listed.
