Comment (by blobfolio):

 Replying to [comment:108 kontur]:
 > Yes, I understand. At any rate, this bug pretty much renders a plugin of
 mine useless, since it is centred around uploading and displaying
 webfonts, all of which, I think, require that the accepted mime type gets
 augmented, and then successfully passes this check - which currently it
 doesn't, or seemingly only sporadic on some installations.

 You could add a filter to your plugin to specifically bypass the issue
 only for font files, either re-implementing a looser `finfo` check (but
 again for font files I don't expect that will work consistently), or just
 rebuilding the ext/type data by passing the original filename back through
 `wp_check_filetype`. Take a look at this function for inspiration:
 https://github.com/Blobfolio/blob-common/blob/master/wp/functions-
 behavior.php#L31  Obviously all the class stuff is a bit out of scope for
 your needs, but if you remove 75% of it you should have what you need.
