Nothing interesting in dmesg when the error occurs.
This was tested using a "UVC 1.00 device Logitech Webcam C925e (046d:085b)". I also have a cheap webcam, "UVC 1.00 device DEPSTECH webcam (0c45:636b)", which exhibits the same behavior.
I also just tested both these webcams using cheese & firefox (one webcam and one client at a time) and all combinations work fine there.
