I have a rather strange problem.
On my production server I'm running apache and mod_wsgi.
I have reports that I generate using reportlab. In some of the reports I
display a corporate logo which is stored in a .png file.
If I start web2py from the command line (using the rocket server) my
reports work fine. When I run them through apache and mod_wsgi I get the
following:
Traceback (most recent call last):

Any idea why this is happening? I'm thinking it has something to do with
the full path of the image file being specified here in the log. Ideas?
