Comment 1 Joe Orton 2022-06-16 10:30:30 UTC

@luhliari looks like an issue in the patch for bug 2075406?

https://gitlab.com/redhat/centos-stream/rpms/httpd/-/blob/c9s/httpd-2.4.53-icons.patch#L38

looks wrong.

Daryl, if you remove the "AddIconByType" line from /etc/httpd/conf/magic does this go away?  I can't see exactly this symptom in a test VM here but I do see errors from mod_mime_magic -

[Thu Jun 16 06:26:55.118757 2022] [mime_magic:error] [pid 4767:tid 4767] AH01524: mod_mime_magic: type AddIconByType /icons/bomb.gif application/x-coredump invalid
