I've never seen similar errors on my systems when using luvcview. This one doesn't even look like a uvcvideo or V4L2 problem on the input side but it looks like SDL is having problems initializing the output window. That still wouldn't explain the failure with headless programs, though. So can you execute echo 64 > /sys/module/uvcvideo/parameters/trace to increase uvcvideo's debug output level and post the syslog output you get after plugging in your camera and trying to run the capture programs?
