Here is an empathy bug that I suspect to come from gabble: http://bugzilla.gnome.org/show_bug.cgi?id=464212
The GNOME bug talks about a Google Talk bug; there's some stuff in Gabble's roster code which seems to be working around Google Talk bugs. Is this still an issue?
I've just reproduced this; it looks like a Google Talk server bug. When we remove someone from subscribe, we send a <presence type="unsubscribe"/> correctly, and GTalk responds with an updated roster item, with subscription="from". But then it sends us another update with subscription="from" ask="subscribed" out of the blue. The remote contact does not, in fact, get asked if we can subscribe again. SEND: ----------------------------------- <presence type="unsubscribe" to="XXX@gmail.com" id="15320294471"></presence> ----------------------------------- RECV [251]: ----------------------------------- <iq to="YYY@googlemail.com/Telepathy3710B4A5" id="5887D34E" type="set"><query gr:ext="2" xmlns="jabber:iq:roster" xmlns:gr="google:roster"><item jid="XXX@gmail.com" subscription="from" name="Will Thompson"><group>Me</group></item></query></iq> ----------------------------------- SEND: ----------------------------------- <iq type="result" id="5887D34E"></iq> ----------------------------------- RECV [267]: ----------------------------------- <iq to="YYY@googlemail.com/Telepathy3710B4A5" id="5887D36B" type="set"><query gr:ext="2" xmlns="jabber:iq:roster" xmlns:gr="google:roster"><item jid="XXX@gmail.com" subscription="from" ask="subscribe" name="Will Thompson"><group>Me</group></item></query></iq> ----------------------------------- SEND: ----------------------------------- <iq type="result" id="5887D36B"></iq>
