Summary: Traceback in pydoc
Initial Comment:
On some objects I have, calling 'help(obj)' raises an
exception. Python 2.4.2, Windows XP.
This is the traceback, together with some info from
pdb.pm():
>>> help(r)
Traceback (most recent call last):
File "<stdin>", line 1, in ?

(Pdb)
The problem seems to be that the TextDoc.docother
method is called with unexpected arguments.
The signature is
docother(object, name, mod, maxlen, doc)
but it is called with the object to document as the
'maxlen' parameter.
