Bug#688480: camera-device-monitor: Don't add NULL devices to the camera list

[KeyofBlueS]

Package: cheese
Version: 3.4.2-2
Severity: important

cheese_camera_device_monitor_set_up_device() will return NULL for non
video devices (ie vbi & radio devices). Emitting the added signal with
such a NULL device, causes it to get added to the camera list, which later
on causes cheese to crash.

** (cheese:24153): CRITICAL **: cheese_camera_device_get_uuid: assertion
`CHEESE_IS_CAMERA_DEVICE (device)' failed
Segmentation Fault
