Comment # 4 on bug 953651 from Dominique Leuenberger

ok - so it's as expected a feature - not a bug.

Apparmor is protecting you from an app that might start random other things.
Here, colord is trying to scan for all kind of file-monitors, when in fact it
only wants to find the ones it supports (which is gphoto2 in the current
situation).

The warning is not nice, but colord can't know about being jailed down.
