I reported at first to: https://bugzilla.gnome.org/show_bug.cgi?id=751590 But it looks like this could be a false positive: /usr/share/applications/epiphany.desktop: warning: value "text/html;text/xml;application/xhtml+xml;x-scheme-handler/http;x-scheme-handler/https;multipart/related;application/x-mimearchive;message/rfc822;" for key "MimeType" in group "Desktop Entry" contains value "multipart/related" which is a MIME type that should probably not be used: "multipart" is a media type that probably does not make sense in this context Thanks for your help
After every "dnf update" in Fedora 24 (every one, not just when epiphany is involved), I see warnings printed out: Warning in file "/usr/share/applications/epiphany.desktop": usage of MIME type "multipart/related" is discouraged ("multipart" is a media type that probably does not make sense in this context) Can we please do something about it? Thanks. Also, shouldn't this be reported against desktop-file-utils instead?
Thanks for reporting. I see downstream wants this in order to handle MHTML. Strictly speaking, application/x-mimearchive is the correct type to use for this, and is what e.g. gvfs-info will return for MHTML files. However, it's not an IANA-registered type, and there seems to be enough confusion about this for multipart/related to be permissible too, so I'll add an exception for it.

FTR we claim to support the following MHTML MIME types in the desktop file: multipart/related application/x-mimearchive message/rfc822 If you think it's wrong to claim support for the other two, I can remove them. I don't know the difference between the different MIME types; I thought they were all the same thing.

I think the above MIME type list should be fine for Epiphany, since you're able to format both e-mails (message/rfc822, often saved with the .eml extension) and multipart e-mails with internal data blobs and references (multipart/related, used for HTML e-mail and other purposes). application/x-mimearchive is just a specific subtype of multipart/related, but it's not officially endorsed as such, and in practice the format is the same, so eh. Might as well list both in case the general case is requested. Thanks for taking the time :)
