Is this policy? If so, it's not one I'm aware of - can you clarify
please?

My understanding of the position was that you have to make sure a proper
package upgrade path is maintained, basically that the versions go in
the right direction and that the package is upgradable. Apart from that
I thought it was at the discretion of the uploader exactly which
releases they wanted to fix. Is that wrong?

Cheers,

Bug description:
  [ Impact ]

  Malformed .desktop files might causes crashes because
  the returned list is NULL.

  [ Test case ]
   - Download and copy in one of your XDG_DATA_DIRS (i.e. ~/.local/share/applications)
     this .desktop file:
     https://github.com/hughsie/appstream-glib/files/1656100/org.gnome.frogr.desktop.gz
   - Run gnome-software it must not crash.

  [ Regression potential ]

  Missing metadata from .desktop files, but really this is just a null-
  checks fix, so not really anything might go worse.
