Reproduce the problem in an interactive Python interpreter
("bin/zopectl debug" on *nix; alternatives for Win*).
Call "pdb.pm()" (or probably better "dm.pdb.zpdb.pm()" ("dm.pdb"
can be found on PyPI)) and go up two call frames.
Look at "obj". With a bit of looks, you see which objects
this is and where it comes from.
