[ Christopher James Halse Rogers ]
* debian/patches/100_rethrow_signals.patch:
  - Drop, in favour of getting LightDM to pass -core to the server. This
    upstream mechanism is significantly more reliable at dumping core in
    my testing. We may later wish to improve this with some processing in
    the apport hook.
