Doctests and pdb

Python debugger (pdb) works little differently when invoked from doctests.

Your locals stack frame is not what you might expect and refers to doctests internals:

(Pdb) locals()
{'__return__': None, 'self': <zope.testing.doctest._OutputRedirectingPdb instance at 0x5a7c8f0>}

Corrective action is to go one level up in the stack:

(Pdb) up
> /Users/moo/mmaspecial/src/Products.PloneGetPaid/Products/PloneGetPaid/notifications.py(22)__call__()
-> import pdb ; pdb.seT_trace()
(Pdb) locals()
