Random failure of calibrating screen with dummy sensor in GNOME

[bigon]

Hello,

I'm getting random failure of calibrating the screen in GNOME (with g-control-center)

colord-session displays:

colord-session[3819]: 09:31:25        CdMain: Emitting Finished(1,profile object path '/org/freedesktop/ColorManager/profiles/icc_ecc2ae8eb9ed26378d9bc8f96db47375_bigon_1000' does not exist for this device

colord shows:

As you can see in the dump file bellow, the device is associated with a non defined profile
