I am running kubuntu 15.04. & plasna 5.4 form kubuntu-ci repo.

KDE Frameworks 5.16.0
Qt 5.4.1 (built against 5.4.1)
The xcb windowing system

Problem started when i upgraded dolphin to 15.08.01
Icons are mess, icon view shows large monochrome icons. Colors are allways like kubuntu default, dolphin doesn't follow kubuntu global colors form system settings. Also, lots of GUI elements are from kde 4
