The cause of this bug is that gs9.27 has removed a command 'execute' which
xdvi uses to display EPS. It exists in gs9.26, so the combination of
xdvik-ja and gs9.26 does not have this bug.
So, restoring this command can fix this bug.
Thus, another solution of this bug is to apply the following patch
to gs9.27.
