Came across a post somewhere in last few days suggesting that this error can also arise due to the infamous expat version mismatch problem. You would though mean you would have had to be using Python 2.4 or older as expat issues shouldn't exist in Python 2.5 as Python correctly namespace prefixes expat code in those latter versions.
The expat problem is described in: http://code.google.com/p/modwsgi/wiki/IssuesWithExpatLibrary Normally one just gets a crash, but feasible that it might cause some sort of run time exception instead depending on how incompatible the expat versions are.
