upgrade of whoopsie fails due to report_crashes=false

Cheers,

I'm using systemd and have set report_crashes=false in /etc/default/whoopsie.

The systemctl service

$ systemctl status whoopsie.service
whoopsie.service - crash report submission daemon
   Loaded: loaded (/lib/systemd/system/whoopsie.service; enabled)
   Active: failed (Result: start-limit) since Fr 2015-02-27 13:52:53 CET; 7s ago
  Process: 22882 ExecStartPre=/bin/grep -sqi report_crashes=true /etc/default/whoopsie (code=exited, status=1/FAILURE)

fails as one would expect; but having these kind of startup requirements in the systemd service is probably a bad idea, especially as it leaves the package unconfigured:

$ sudo dpkg --configure --pending
Setting up whoopsie (0.2.39ubuntu0.2) ...
Job for whoopsie.service failed. See 'systemctl status whoopsie.service' and 'journalctl -xn' for details.
invoke-rc.d: initscript whoopsie, action "start" failed.
dpkg: error processing package whoopsie (--configure):
