Can you file a separate bug for the SDL1 backspace problem - it was not intended to cause problems like that.
Unless you want it tracked in a bug I'm happy with a fix submitted to the list eventually without being separately tracked on launchpad. I would've reported this on the mailing list normally but since this is also relevant here due to SDL2 also not uasable beacause of this bug I've commented here so people affected by this know about both problems.
