Bug Description

Cheese fails to capture video from the webcam after taking a photo. Running Cheese from the terminal prompts the following error:

libv4l2: error setting pixformat: Device or resource busy

(cheese:5170): cheese-WARNING **: Device '/dev/video0' is busy: gstv4l2object.c(2838): gst_v4l2_object_set_format (): /GstCameraBin:camerabin/GstWrapperCameraBinSrc:camera_source/GstBin:bin18/GstV4l2Src:video_source:
