variables defined twice in config files lead to crash

[Yves-Alexis Perez]

Hi,

it seems that the recent changes to the config files handling (maybe linked to the --show-config option) actually cause crashes. When a variable is set twice, LightDM crashes at startup.

It seems also visible with --show-config:

root@scapa:~# lightdm --show-config
   [SeatDefaults]
A greeter-session=lightdm-greeter
A greeter-hide-users=true
A session-wrapper=/etc/X11/Xsession

Sources:
A /usr/share/lightdm/lightdm.conf.d/01_debian.conf
B /etc/lightdm/lightdm.conf

Uncommenting greeter-hide-user=true in /etc/lightdm/lightdm.conf:

root@scapa:~# lightdm --show-config
   [SeatDefaults]
(null) greeter-session=lightdm-greeter
B greeter-hide-users=true
(null) session-wrapper=/etc/X11/Xsession

Sources:
[Invalid UTF-8] (null) \x8861\xe3m\x7f
B /etc/lightdm/lightdm.conf

This is LightDM 1.10.2 by the way.
