Thanks for the bug report; I've fixed these problems in the standalone 
version (0.1.2 on the cheeseshop) and in the Python 2.5 trunk.

Web-SIG folks take note: wsgiref.validate is based on paste.lint, so 
paste.lint has the same problem.  That is, errors won't be raised if the 
code is run with -O.

As a side effect of fixing the problems,  I found that some of the 
wsgiref.validate (aka paste.lint) asserts have improperly computed 
messages.  Instead of getting an explanation of the problem, you'll instead 
get a different error at the assert.  I fixed these in wsgiref.validate, 
but the underlying problems presumably still exist in paste.lint.
