Hm, I didn't think we'd done anything that would *fix* that between 4.08
and 4.99; I'd like to make sure I fully understand what's going on and
make sure it's really fixed and will *remain* fixed.

Please could I see the full debug output of 4.99 when you connect with
the '-v' option on the command line? And also 4.08, preferably. Thanks.
