And while I am thinking about it, if this is needed on Trusty, I assume
that Utopic and the lts-backport thereof are also affected?  I assume we
should be patching there too?  Again hopefully this will come out via
stable.  I've nominated the bug to the various packages and series that
seem relevant, and marked it up for commit tracking (so if they come in
via stable it will also get closed out).
