Bug#878000: More details - there is no package creating the required "assets" subdirectory

[wzab]

I have checked, that there is no package providing neither
/usr/share/themes/Breeze/gtk-2.0/widgets/../assets
nor
/usr/share/themes/Breeze/gtk-2.0/assets :

root at wzab:/home/wzab# apt-file search
/usr/share/themes/Breeze/gtk-2.0/widgets/../assets
root at wzab:/home/wzab# apt-file search
/usr/share/themes/Breeze/gtk-2.0/assets
root at wzab:/home/wzab#

With best regards,
Wojtek
