[pkg-cinnamon] Bug#871460: another example

[Krzysztof Słychań]

I track testing/sid amd64 and update my system daily. Had to reboot 
today, and was surprised that the stock Debian wallpaper appeared 
instead of my favourite one.
Tried to change it in cinnamon-settings, to no effect.

I also noticed that a dark GTK3 theme stopped working as well (Firefox 
and Thunderbird used a standard bright gray theme).
Keys assigned to launch a web browser or email client didn't work too. I 
reassigned them to custom launchers.
I don't like any audio notifications for Cinnamon or FF/TB and was 
surprised to hear a sound when new mail arrived too...


I read suggestions in this bug report and can confirm that removing the 
gnome-settings-daemon (probably a leftover from the past) actually helps.
No more problems, the old wallpaper and themes are back.


The culprit:
