Failed to find device that matches f0afd74779f78cf97e8036fe4e643a75: 
property match 'OutputEdidMd5'='f0afd74779f78cf97e8036fe4e643a75' does not

As you can see "f0afd74779f78cf97e8036fe4e643a75" is present in the current 
profile name for the monitor, but colord reports a different EDID for the 
monitor: icc-d376f967adbbeaee5dfd4ad20d82f302

Maybe a bug in xiccd?
