As a workaround, you want to use ${@:-}, not ${@:+}.

[Joey Hess]

Since debconf's confmodule uses $@, to support being called
from set -u maintainer scripts it would need to either
set +u (not very nice since that would also affect its caller),
or use ${@:+}. But this bug prevents the latter; so debconf's bug,
#522255, is effectively blocked by this bug in bash.
