[Moin-user] Problem with mod_wsgi

[Emilio Lopes]

I'm the admin of a MoiMoin-Wiki (currently 1.8) in our company's intranet.

We had the problem that small images as attachments (file size, not
picture size) did not appear at all.  Also, apparently unrelated,
drawings did not work either: there was some error message in the java
console that it was "expecting a string in line 1" or something like
that.

I thought it was a problem with apache and tried turning off the
options EnableMMAP and EnableSendfile (known to cause such symptoms)
to no effect.  A small pure html test page showed that apache has no
trouble serving small files.

It was clearly a MoinMoin problem, but astounding no other MoinUsers
are noting it!  It turned out it is indeed a bug in mod_wsgi:

Upgrading to version 2.5 (from 2.3) solved the problem.

I'm writing this here for the benefit of other MoinUsers having the same
problem.  Maybe one could document it somewhere in the MoinMoinWiki; I
couldn't find an appropriate page for this.
