When enabling the mod_mime_magic module, the clause | <IfModule mod_mime_magic.c> | MIMEMagicFile share/magic | </IfModule> (/etc/httpd/conf/httpd.conf:552) will be evaluated. Effectively it tries to read `/etc/httpd/share/magic'. This fails because the magic file is installed in /etc/httpd/conf/magic. Either change the MIMEMagicFile entry to this position or let it point to the more extended /usr/share/magic file. Because both magic files are having the same purpose, one of them seems to be superfluously (see #14741 also).
nalin: Make sure it reads /usr/share/magic.
Should be fixed in apache-1.3.12-23 and later.
