help('modules') with PyQt4 installed causes interpreter to fail and dreampy must be restarted

[patcorwin]

What steps will reproduce the problem?

1. I ran help('modules')

What is the expected result?
I might actually have the results, after a few seconds I have "[About 174 more lines. Double-click to unfold]" but the error reporting window popped up.

What happens instead?
Error window popped up. After submitting the bug it looks like it ran ok (hard to tell with so many modules) but the traceback was for PyQt4

Traceback (most recent call last):
