--- Comment #4 from Kalev Lember klember@redhat.com --- Oh, sorry, I totally missed this ticket.
Looks like what happened here is that gmime upstream has stopped uploading gmime tarballs to https://download.gnome.org/sources/gmime after 3.2.7 release, so the fedora gnome package maintenance scripts didn't pick the updates up any more.
