gmail issues with msn, icq and other jabber-transport

В данный пост будут отправляться все, кто жалуются на работу jabber-транспорта icq.darkk.net.ru с учётными записями на gmail.com. Проблеме уже несколько месяцев и, судя по всё еще живому треду на форме саппорта, она до сих пор не исправлена. Со своей стороны я, кажется, сделал почти всё, что мог — остаётся разве что отослать резюме в Google. :-)

Если у кого-то относительно этого бага есть идеи получше — welcome!

Subject: gmail issues with msn, icq and other jabber-transport

There are numerous topics at google support forum about impossibility to
register as a transport user using gtalk account.

Here is[1] one of them that is a month and a half old, but there are
much more topics on the issue.

[1] http://google.com/support/forum/p/Talk/thread?tid=0697c2950e983d95

I've just tested and I've found out that it's still impossible to
register as a transport user using google account.

I attached XML dumps of session from transport side (gmail-pyicqt.xml)
and from jabber client side (gmail-psi.xml).
The dumps were passed through `xmllint --format` to ease reading of the
dumps.

As you can see presence stanza is sent by pyicqt but it's not received
by jabber client, so transport can't subscribe to user's presence and so
it can't operate properly. Moreover, no error is returned to transport.

I can also provide pyicqt logs, full session dumps for jabber client and
pcap-formatted dumps, I don't attach them as they have no relevant
information.
