RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Version-Release number of selected component (if applicable):

httpd-2.4.53-1.el9.x86_64

How reproducible: always


Steps to Reproduce:
1. Request resource from server that does not set a Content-type header
2. Observe the message logged
3.

Actual results:

AH01538: mod_mime_magic: invalid type 0 in mconvert().

Expected results:

No message logged

Additional info:

The previous httpd version did not have this issue. 2.4.51-8.el9

@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 06:26:55.118733 2022] [mime_magic:error] [pid 4767:tid 4767] AH01521: mod_mime_magic: offset AddIconByType /icons/bomb.gif application/x-coredump invalid
[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

Thank you for the response.
