It turns out this is a bug in intltool-merge, which doesn't behave correctly when using rfc822deb merging for a file whose very first field requires translation handling.
Easy enough to work around in update-notifier by reordering the fields, so I've committed a fix to do that; but the root bug ought to be fixed as well.
