Since you are already setting WSGIApplicationGroup, if you aren't using
mod_php either, then read:

http://code.google.com/p/modwsgi/wiki/DebuggingTechniques#Debugging_Crashes_With_GDB

and see if can get a stack trace.

BTW, you don't need:

WSGIRestrictStdin Off
WSGIRestrictStdout Off

That is default for mod_wsgi 3.0+.
