Running MW 1.25.1 and one of my Users just noticed that files with the extension .patch no longer are upload-able. The wiki is configured with $wgFileExtensions to include 'patch' and there are no BlackListed filetypes set. This used to work, not sure if something changed that I missed.

The error given is "File extension ".patch" does not match the detected MIME type of the file (chemical/x-mdl-rgfile)."

or also: ""File extension ".patch" does not match the detected MIME type of the file (text/plain)"

Is there a way to allow .patch files to be uploaded?

Thanks Bill
