Colord suddenly takes 100% of CPU

[Maakuth]

I'm not sure what happened, but I noticed my CPU fan humming loudly. I checked with top and noticed that colord used 100% CPU. After a couple of minutes I grew impatient and just killed it. I haven't noticed any difference in the system's operation after killing it.

Same here today. 100% of CPU just after log on. I killed it, and nothing was affected by it.

Initially marked myself as affected, but I haven't seen this for at least half a year (maybe even more) on 12.04.
