Comment 28 for bug 1377847

This bug still happens in a freshly installed, fully patched Ubuntu - on both version 15.04 and 14.04. Hadn't tested on 14.10
On both versions the session is not locked after the time specified in unity-control-center.
ctrl+alt+L works on both

Ubuntu 14.04:
unity-settings-daemon 14.04.0+14.04.20140606-0ubuntu2
unity-control-center 14.04.3+14.04.20140922-0ubuntu1
gnome-desktop3 3.8.4-0ubuntu3.1

Ubuntu 15.04:
unity-settings-daemon is 15.04.1+15.04.20150408-0ubuntu1
unity-control-center is 15.04.0+15.04.20150410-0ubuntu1
gnome-desktop3 is 3.14.1-1ubuntu2

I think the "Fixed Released" state needs to be reverted
