This is probably the problem with autoindex I briefly mentioned. To do
an index it actually does a sub request as far as the fixup handler
phase for every item which it might list in the index to determine if
it has access rights and should be listing it. If you have handlers
for these phases it will trigger them for the subrequest as well which
might cause issues. One can detect if such a handler is called in
subrequest by looking whether req.prev or req.main (cant remember
which), is not None.

When I get a chance to at least get directory index to week as you
indicate what you want, then we can start stepping through these
others issues.
