Bug#856887: sddm default configuration is not properly taken

[Miguel Angel <mianrojas@gmail.com>]

Package: sddm
Version: 0.13.0-1
Severity: important
Tags: upstream

Dear Maintainer,

sddm default "blue configuration" is not taking properly when the
packages is upgraded to version 0.14 or above (bad theme and wrong
configuration)

Downgrading to version 0.13 makes sddm usable again with the
default theme properly setup. Curious thing is when you lock your screen
with 0.14, the right blue default theme is displayed (?), but not in the logout.

If you need screenshots, just let me know, but it is very easy to
reproduce.
