We need to add an import for HeaderParser on python 2.4; email.Parser
appears to contain the right stuff.

Hi,

I applied the patch, actually ran git pull (saw that the new models.py
hadd your additions), then manage.py syncdb (verified that the new
entries went into patchwork_patch, e.g. pull_url), then restarted
httpd, but still getting the headerparser import error when clicking
the mbox link for a patch :

btw, did test that the new imports work in python 2.4, just some other
error in scope somewhere?

Hi Sabuj,

> I applied the patch, actually ran git pull

The git repo does not include this change, you'll need to apply the patch 
manually.

Or did you do that?

Ahh, I took a quick glance at the changes in models.py after git pull,
saw "Python 2.4 compatibility" and thought that you had merged it .
Seems like the git pull was basically just missing the one line :

from email.Parser import HeaderParser

After adding that line, the mbox link now works .

OK, thanks for testing. I've committed this patch.
