Bug#1091844: dolphin: No icons in a Gnome session

Turns out no, I did not! I guess I used "--no-install-recommends" at some point
to avoid pulling in too much of KDE when I just want to use a KDE application, 
not the entire desktop environment.

After installing that, Dolphin now has icons. Thanks a lot!

Maybe it would be worth adding this as a "Depends:" somewhere, e.g. the breeze 
icon set or wherever the KDE Qt6 platform theme lives?

Kind regards,
Ralf
