Are you able to test from a bzr or svn checkout? If so, can you try this 
against the
latest trunk? The reason I ask is that I can't reproduce this problem.

If that's not possible for you, I will update this ticket when I've released 
the next
version of PyRRD, so that you can download it from PyPI.

Thanks!

The problem was deeper and apache/mod_wsgi related. With nginx+flup, 
nginx+tornado, 
nginx+fastcgi everything works perfectly and only with apache+mod_wsgi sample 
code 
raises that exception. I think we can close this issue.
