I was able to duplicate this on my Ubuntu 12.04 machine. I see that 127 is the Delete key. I found several referecnes that explain this is an issue with Linux - when the backspace key is pressed, it sends the delete key instead. I have included some links below, which describe the problem, and also offer some workarounds.
