The db field of minor mime ( in filearchive and image tables ) is currently varchar(32), but this is not large enough for real world situations. Example is http://wikimediafoundation.org/wiki/File:Wikimedia_Five-Year_Targets.ods (file size: 19 KB, MIME type: application/vnd.oasis.opendocument.spreadshe)
I briefly glanced over the relevant RFCs and saw no specific maximum size mentioned, so I guess we should make it varchar(255).
