Still no <Directory> container for '/proj/tiddlyweb/apache' saying
that Apache is permitted to use stuff in that directory. You only have
it for the static sub directory. If it is working without it, your
Apache configuration is else where opening up access to that part of
the file system. You perhaps really need to review the security of
your Apache configuration as you are possibly opening up a lot more
directories than you should. It is a common mistake to open up the
whole file system, which is not a good thing to do.

This could be because the script is being run as CGI script. This can
occur if elsewhere in your Apache configuration you have:
AddHandler cgi-script .py
This is why the mod_wsgi documentation always uses a .wsgi extension
rather than .py so as to avoid these sorts of problems.
Whether this is actually the case one can't easily tell because you
haven't set:
LogLevel info
so extra debug from mod_wsgi not available. See:
http://code.google.com/p/modwsgi/wiki/DebuggingTechniques
With that enabled, can then see if script is actually being handled by
mod_wsgi and into which process it is being loaded, embedded mode
process or daemon group process.
The error can also be caused by a crash in the mod_wsgi daemon
process.

For the causes of crashes in mod_wsgi see:
http://code.google.com/p/modwsgi/wiki/FrequentlyAskedQuestions
http://code.google.com/p/modwsgi/wiki/InstallationIssues
http://code.google.com/p/modwsgi/wiki/ApplicationIssues
and search for stuff about core dumps, crashes and segmentation
faults. There could be a range of issues that could cause this, in the
main resulting from conflicts between versions of shared libraries
used.
Again, if had LogLevel set so extra debug information output, then
could be easily determined if that was a mod_wsgi daemon process that
crashed.
