Subject: [PATCH] application/octet-stream is for arbitrary binary files

application/octet-stream mime-type is used for arbitrary binary files, so the best guess at opening those kind of should be based on the extension. before this all of this kind of files were tried to be opened with zathura, now it is the last resort in case the file extension is unknown.
