I've changed Image.py as suggested in the line above but I was still getting
some strange behaviour so I pursued it a little bit further. I encountered
the following strange behaviour when using the debugger to step through the
code:

The image I'm looking for has:

 Last-Modified: Wed, 15 Mar 2000 19:02:17 GMT

Upon executing:

 ZPublisher.Zope('/path/to/image', d=1)
 
and stepping into the debugger I set:
 
 environ['IF_MODIFIED_SINCE'] = 'Wed, 15 Mar 2000 19:02:17 GMT'
 
when I get to lib/python/OFS/Image.py(line 188) I get the following strange
results:

> OFS/Image.py(188)index_html() 
-> if last_mod > 0 and last_mod <= mod_since: 
pdb> print mod_since, last_mod 
953146936 953146937                       <<<< Something is wrong! mod_since
                                               should equal last_mod

953146936                                    <<<< I still don't believe this.

953146937.0 
pdb> print header

953146936L                                   <<<< long also does it!?

I'm completly baffled by this, how can int/long be interacting with
DateTime(header).timeTime() to produce this error?
