Brian Warner and I discovered that issue yesterday, too.  We  
determined that if you install the egg (with easy_install or with a  
setuptools-powered ./setup.py install) in unzipped form then the  
source file names get rewritten so that your stack traces come with  
source lines.

If you have a package which requires stack traces to come with source  
lines, then you could pass "zip_safe=False" to the call to setup().

I would prefer that zip_safe=False were the default and that either  
the producer or the consumer of a package had to specifically choose  
zip_safe=True in order to install eggs in zipped form.

I've opened a ticket on my setuptools trac:
