Thats not what I wrote. CompICC does not break applications, which rely on 
* the _ICC_PROFILE(_xxx) in X spec
* non colour managed applications
This happens by honouring the net-color spec through the colour server.

Calibration and profiling applications are affected (unfortunedly). I 
do not know how to avoid this. Moreover I doubt it would be even 
possible. These applications need to use eigther hacks or deploy the 
net-color spec for opt-out of colour management.
