I noticed something this morning that may pertain to this bug report. I'm sure it's been happening for quite awhile but it just happened to catch my eye. Syslog reports:

Jan 14 11:38:50 localhost colord[1519]: (colord:1519): Cd-WARNING **: failed to get session [pid 9641]: No such device or address

Coincidentally pid 9641 is

9641 root 20 0 94600 8728 6316 S 0.0 0.2 0:00.02 cupsd

It also seems that the pid of cupsd changes every six minutes
