I'm not able to reproduce this and looking at the code, I'm not seeing how
it could happen either. FWIW, the text in the message has changed since the
version you're using so maybe there was another bugfix at that time, too.
Perhaps upgrading will help. Or maybe there's something important in what
you clicked that I am missing that would help me understand the bug.
