The problem occurs like this. You walk away from the machine and then
one of these configuration screens comes up, and then the monitor blanks
out for power saving. Next you come back and press space bar and then
whatever question was pending goes through before you have a chance to
answer it. It's like hitting the space bar acts as a return and the
default action gets executed.
If you feel strongly about this, file a bug on whiptail or change to a
different debconf frontend; only the dialog frontend is likely to behave
this way, it probably sometimes interprets space as selecting a button
in the UI.
