MSNP12: disconnecting after UUX or QRY

While working on an implementation of MSNP12 for PHP, I found that the
Notification Server is disconnecting me (signing me out) as soon as I
send a UUX command with the PSM and MachineGuid. It does not sign me out
if I do not try to set my PSM etc, by omitting the UUX.

>>> = Send, <<< = Receive

[ Tweener Authentication etc, then: ]

</MachineGuid></Data>
<<< UUX 9 0
[ Server closes connection ]


I also get disconnected after having received a confirm command of a
successfully completed QRY challenge:


[ Normal protocol connection, including switchboard invites, etc.,
everything just working fine... until now: ]

<<< CHL 0 21078281041487922537
>>> QRY 15 PROD0114ES4Z%Q5W 32\r\n
24ae42ad2504abd89f67997146c293c7
<<< QRY 15
[ Server closes connection ]


Note:
I do calculate the hash correctly, as I am *not* receiving
a 540 error, but a successful "QRY" reply before the notification server
disconnects.

Any ideas why the server is disconnecting me in these 2 cases?
Thanks for your research,

Solved.
Jonathan Kay pointed me to a thread at Fanatic stating that problems
will arise when I add an additional \r\n to a payload command, like UUX
and QRY are.

Thanks mate!
