Same problem here with Dell XPS 12 9Q33 and Ubuntu 14.04 unity.

Cheese initiates but closes with the following message:
libv4l2: error got 4 consecutive frame decode errors, last error: v4l-convert: libjpeg error: End Of Image

(cheese:3426): cheese-WARNING **: Internal data flow error.: gstbasesrc.c(2865): gst_base_src_loop (): /GstCameraBin:camerabin/GstWrapperCameraBinSrc:camera_source/GstBin:bin17/GstV4l2Src:video_source:

I've installed guvcview and it works partially on it (get some
horizontal error lines on the video). But still does not work on any
other place.

Any ideas?
