Hmm after perusing that file some more I found postscript and pdf appear to be misclassified.
I think you can just about make the case for RTF being a subtype of text/plain given that you read it when you strip away the markup in a text viewer like vi. However binary formats like application/pdf and application/postscript are no more readable in a text viewer than a binary MSWord 6 document (and Word documents aren't a subtype of text/plain). ** Also affects: shared-mime-info (Ubuntu) Severity: Normal Priority: (none set) Status: Unconfirmed -- abiword eats memory (possible OOM) and hangs when opening PDFs https://launchpad.net/bugs/44523 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
