StackOverflowError in 2.1

[Ralph Goers]

I wanted to mess around with some of the input modules so I brought up 
the input module page in the sample site.  However, it dies with a 
StackOverflowError. I then checked out the latest to another one of my 
computers (with Linux instead of Windows) and got the same error.  
Unfortunately, no stack trace is presented.  I've tried going directly 
to some of the samples on that page and can't get anything to work.
