OK, I hate to admit this one, but in case anyone else ever encounters this very puzzling case: the trouble was that I had managed to chown / (as well as /home) to pi:pi while copying files to /home/pi. The problematic thing was /, so doing "chown root:root /" was sufficient to fix the B3 login problem, while doing "chown root:root / /home" would fix the whole mess.
