kubuntu 15.04, Qt 5.4.1

As a result I can't assign icc profile to a display device.

Reproducible: Always

Steps to Reproduce:
1. kubuntu with plasma5
2. install colord and colord-kde packages
3. check System Settings

Actual Results:  
No CMS colord-kde entry in System settings => no possibility to assign profiles to devices.

Expected Results:  
CMS colord-kde entry in System settings => possibility to assign profiles to devices.

Description: system service to manage device colour profiles -- system daemon
 colord is a system service that makes it easy to manage, install and generate
 colour profiles to accurately colour manage input and output devices.
 .
 It provides a D-Bus API for system frameworks to query, a persistent data
 store, and a mechanism for session applications to set system policy.
 .
 This package contains the dbus-activated colord system daemon.

Moreover I wonder if Severity of this bug shouldn't be "Major" - currently kubuntu has limited functionality for photographers and computer graphic.
