Hi,
I have a small Pyramid app which worked fine until yesterday. In one
certain view I get the following stack trace:
Traceback (most recent call last):
File "/usr/lib/python2.7/wsgiref/handlers.py", line 86, in run

----------------------------------------
I did only some minor changes regarding the configuration of my app and
already tried to revert them, but without success. I'm running the
application via pserve and have added some brute force print statements for
debugging. But even with those I was not able to track down the exact
problem. I found
http://stackoverflow.com/questions/21059640/wsgiref-error-attributeerror-nonetype-object-has-no-attribute-split,
where I've read that this error might occure, if the wsgi app returns
results in the wrong way.
My guess is, that something strange is wrong with my code and that the
above error is just a follow up error, which hides the real problem. So I'm
aware that this is a quite vague question, but does anybody know the error
message above and could give me a hint, how to track down the real problem?
cheers,
Achim
