Can reproduce on dmaster.demo. I don't see it in 5.22 but do see it in 5.24 and up. Don't have a 5.23 handy.

1. Create at least 2 groups with the mailing list checkbox checked.
2. Go to New Mailing.
3. Pick one group.
4. Open the group dropdown again and scroll down.
5. It even lets you select it.

In drupal watchdog there is this:

This might be violating a higher mathematical law here too - it's not possible to exclude the null set, since the null set is a subset of every set. (Source: Math)
