Hard code freeze break request [gcalctool]

[Robert Ancell <robert ancell gmail com>]

Hi,

A bug [1] has been reported against gcalctool 5.27.92 showing that
keyboard accessibility does not work.  This is a regression from
previous stable gcalctool releases.

The attached patch fixes this problem by stopping the keyboard event
for spacebar from being consumed when the buttons are in focus.  I am
the maintainer of gcalctool and I approve this patch.

Thanks,
