#111, more diagnostic printout

please try this and email error console printout to me (ctrl shift j, put cursor inside box, ctrl A, ctrl C, then copy into #111 or email to me).

many thanks.

Before trying the keybinding: there might be a double key: tools-> nostalgy++, tab keys, at the bottom: is there a secong go_back or _back? This has a delete on the right side, please delete this.

Do the keys now come up at start?

Looking at error console printout, Linux and Mac seem to have different problems.
