I'm taking my words back, please confirm:
all base/darko/jolla-ambient(from earlier sailfish sdk) themes currently do -not- have folders that this mlocalthemeclient is scanning:
./meegotouch/images/ has wallpaper and image files (png and jpg)

there are no such folders that mlocalthemeclient is -only- looking into, omitting the main parent one:
./meegotouch/images/theme
./meegotouch/images/backgrounds

I would just remove the scanning of those two folders above as none of themes are ever using it, and currently without this patch mlocalthemedaemon is completely funcionless.
