WxCam starts up OK but freezes if I select "Frame Size" from the Settings menu.  The video is displayed in a  very small window on startup.  If I make the video full screen it does not freeze but it is obviously a small picture scaled up (very blocky pixels).  All the required libraries are present.  I will be glad to provide more info if you need it.  The camera is the Logitech Quickcam Pro 9000.  Here is the output:

mike@Dell64:~$ wxcam
Determining video4linux API version...
Using video4linux 2 API
VIDIOC_ENUM_FRAMESIZES: Invalid argument
V4L2_CID_GAMMA is not supported
Determining pixel format...
pixel format: MJPEG
Found V4L2_PIX_FMT_MJPEG pixel format
pixel format: YUV 4:2:2 (YUYV)
Found V4L2_PIX_FMT_YUYV pixel format

If I select Frame Size from Settings menu here the picture freezes and the CPU become about 50% busy until I force quit.

This may be unrelated but wxCam actually crashes if I use an older webcam.  Cheese works OK so I know the camera works but it is a very old Logitech Quickcam - the new camera is the one I really care about for now.  The crash occurs on startup and shows this output:
