[Mediawiki-l] Plus-character in file names prevent thumbnail creation

The following is our apache config for the site:

  Alias /wiki   /var/www/v-species/w/index.php
  Alias /openmedia     /var/www/v-species/o/index.php
  <IfModule mod_rewrite.c>
  RewriteEngine  on
  RewriteLogLevel 0
  # permanent redirect "www.xxx.net/wiki/" to "xxx.net/wiki/" ALL OLD URLs
  RewriteCond  %{HTTP_HOST}   !^species-id\.net [NC]
  RewriteCond  %{HTTP_HOST}   !^$
  RewriteRule  ^/?(.*)        http://species-id.net/$1 [L,R=301,NE]
  # redirect wrong uppercase:
  RewriteRule  ^(.*)(/WIKI/)(.*)$   $1/wiki/$3 [R]

  # Thumb generation (see Manual:Thumb.php)
  RewriteRule ^/w/media/thumb/[0-9a-f]/[0-9a-f][0-9a-f]/([^/]+)/([0-9]+)px-.*$
/w/thumb.php?f=$1&width=$2 [L,QSA]

  RewriteRule ^/o/media/thumb/[0-9a-f]/[0-9a-f][0-9a-f]/([^/]+)/([0-9]+)px-.*$
/o/thumb.php?f=$1&width=$2 [L,QSA]

I very much appreciate it if you can see what needs to be changed so
that "&" and "+" are working. We have analyzed it and searched for
people having similar problems. Both work fine for uploading and full
size image, but thumb generation fails. We use a standard imagemagick
thumb generator, nothing special as far as I know. Thumb generation
from command line works fine, which is why we suspect the apache
rewrites to be involved.
