Comment 28 for bug 29787

That link is not the same issue; it has to do with the terminfo and stty disagreeing with eachother. Fixing either the terminfo or stty should fix the problem (they agree with each other in upstream screen AFAICT; they disagree in some packages).

This bug has to do with vte-based terminals, such as xfce4-terminal and TerminalScreenlet, sending ascii NUL (^@) for backspace when they are set to auto-detect what to send for backspace, which is a different issue. Other backspace problems are nearly always misconfigurations of the environment. They will always exist, because such misconfigurations will always occur easily.
