Description Karel Srot 2015-09-16 08:38:14 UTC 
Description of problem:

When a user wants to shut down a system while the shutdown is prevented by systemd inhibit lock the message displayed is not very helpful in clarifying the reason for the lock (or that there is any lock at all)

The actual message is:
With RHEL-7.1, gnome-shell-3.8.4-45.el7.x86_64
Authentication is required for powering off the system while an application asked to inhibit it

With RHEL-7.2, gnome-shell-3.14.4-24.el7.x86_64
no window/message is displayed at all

Version-Release number of selected component (if applicable):
gnome-shell-3.8.4-45.el7.x86_64
gnome-shell-3.14.4-24.el7.x86_64


How reproducible:
always

Steps to Reproduce:
1. ### set up an inhibit lock, e.g. by installing rpm-plugin-systemd-inhibit and executing rpm/yum transaction or
# systemd-inhibit --what=shutdown --who=root --why="because I can" --mode=block sleep 60
2. try to shutdown a system from gnome-shell
3.

Actual results:
Authentication is required for powering off the system while an application asked to inhibit it
or
No information at all that the shutdown was prevented (gnome-shell-3.14.4-24.el7.x86_64)

Expected results:
Authentication is required for powering off the system while an application asked to inhibit it:

     Why: Transaction running
