Well... nullglob *and* failglob are pretty much at odds with each other. I'm
not sure what you expect to happen.

This seems a bit more odd to me.

    $ > foo
    $ declare -A foo=([bar]=*)
    $ echo "${foo[bar]}"
    *
    $ shopt -s nullglob
    $ declare -A foo=([bar]=*)
    $ echo "${foo[bar]}"

    $ echo "$BASH_VERSION"
    4.2.45(2)-release

That looks like a bug, maybe.
