Check in the patch proposed by Ben Hayden (benjhayden) for issue

#1550: help('modules') broken by several 3rd party libraries.

Tested with Python build: trunk:54235:59936M -- the reported error
occurs with Django installed (or with any __init__.py present on
the path that raises an exception), and such errors indeed go away
when this change is applied.
