[Bug 1084118] Re: update-notifier crashes on (unity) session startup

[Brian Murray]

Thank you for taking the time to report this bug and helping to make
Ubuntu better.  This crash occurred in update-notifier's monitoring of
disks for a disc that contains Ubuntu packages.  Beginning with Ubuntu
13.10 this code has been replaced with an upstart user session job and
subsequently this crash can no long occur.  Therefore this bug is being
marked as invalid.

** Changed in: update-notifier (Ubuntu)
       Status: Confirmed => Invalid

** Changed in: update-notifier (Ubuntu)
   Importance: Undecided => Low

  The same happens with the command ' sh -c /usr/bin/update-notifier '.
  There is only one more message : ' Segmentation violation '.
