After a few seconds the display color profile is back to default (Fedora 20, KDE4)

Description of problem:
I have installed a color profile (called “P170HMx, precise matrix”) for my display. This is what I see in KDE color settings:

Devices

  • Clevo - P170HMx
    • Default: P170HMx
      v P170HMx, precise matrix
      the installed profiled is ticked and when I start a KDE session, this profile is applied but only for a few seconds and then the default profile is applied automatically. However, even if the default profile is automatically applied, the installed custom profile is still ticked in KDE color settings.

Version-Release number of selected component (if applicable):
colord-kde
Architecture : x86_64
Version : 0.3.0
Révision : 2.fc20

How reproducible: always

Steps to Reproduce:

  1. install a profile et select it so that it is applied
  2. leave the KDE session
  3. start a new KDE session

Actual results:
the custom profile is applied only for a few seconds

Expected results:
the custom profile is applied for the whole session.

Additional info:
No bug with nouveau driver (after yum erase *nvidia* and reboot).
