Comment 10 for bug 961611

These files contain privileged information. So instead of changing the access to 0664 I set the group to 'admin' and the mode to 0640:

 -rw-r----- 1 root admin 161 Jun 13 12:18 private-ppa.launchpad.net_commercial-ppa-uploaders_fluendo-plugins_ubuntu.list
-rw-r----- 1 root admin 163 Jun 13 12:18 private-ppa.launchpad.net_commercial-ppa-uploaders_world-of-goo_ubuntu.list

I have added the landscape user to the admin group:
 ayers@schiefer:~$ getent group admin
admin:x:119:ayers,landscape

Yet it seems that the landscape user still doesn't have read access to these files as the crash still happens with the permission denied error message. I suppose that the issue might be related to the fact that process running as system users somehow do not have access to their group privileges?
