I presume you got the subsequent message with the details of the bug.

Someone wrote

    It's because re-builder declares as "invalid" any regexp that matches the
    empty string.

So I suggested:

    Is there a way it could visibly but not annoyingly notify the user
    about this, instead of rejecting such a regexp?
