Added face detection via configure audio ->advanced configuration->add which has presence of user listed, but it seems to work erratically. I get this message also at the bash prompt: image@image-test-k12-0:~$ QLayout: Attempting to add QLayout "" to CompoundConditionSettings "wgRecognitionConditions", which already has a layout QCoreApplication::postEvent: Unexpected null receiver QLayout: Attempting to add QLayout "" to CompoundConditionSettings "wgRecognitionConditions", which already has a layout QCoreApplication::postEvent: Unexpected null receiver HIGHGUI ERROR: V4L/V4L2: VIDIOC_S_CROP QDBusConnection: session D-Bus connection created before QCoreApplication.

Okay, taking back this bug. The debug output doesn't look too worrisome. What exactly do you mean by "erratically"? Depending on your webcam and lighting conditions the detection might not be entirely stable but should be fairly predictable.
