help('modules') crashing? Not sure how to fix

I was trying to install a module for opencv and added an opencv.pth file to the folder beyond my sites.py file. I have since deleted it and no change.

When I try to run help('modules'), I get the following error:

Please wait a moment while I gather a list of all available modules...

What gives?!

This happens because help('modules') imports all modules, which can result in a lot of unsentineled code being executed. There's nothing you can do short of reporting bugs in every single package that causes this (opencv in this case) and wait for them to fix it.
