You're absolutely right...and I should have thought of looking into leptonica first! Thanks for the reply.
I kind of figured out an answer for my own purposes more or less. I just wanted to have something googleable in case other people saw this error and were trying to figure it out. So if you googled your way here, It looks like the answer (from the link, and my own testing) is that an image of >10 billion pixels is too big (at least on my windows 7/tesseract 3.01 setup).
