I would agree with that. The camera is sending "empty" 0x0 pixel, 0-channel images, probably because it didn't initialize correctly. A few other people have had basically the same problem, so we've been trying for the past week to reproduce this, but we haven't got it to happen with at least an actual error message about the camera.

One this I would recommend trying out is the v1.3 release candidate 1. The only thing it changes about cameras is that they now try to restart if they don't work the first time. The problem might be as simple as cameras not connecting the first time because they're initializing or something weird.

Let me know if this helps.
