XML stanza issue: /remove rejected by prosody (and maybe other servers)

[infinity0]

When trying to remove someone from my roster, I'm getting the following:

[17:23:54] OUT TLS: <iq type='set' id='8'><query xmlns='jabber:iq:roster'><item subscription='remove' jid='[email protected]' xmlns=''/></query></iq>
[17:23:54] IN TLS: <iq id='8' type='error' to='[email protected]/xxxx'><error type='modify'><bad-request xmlns='urn:ietf:params:xml:ns:xmpp-stanzas'/></error></iq>

I'm not sure if this is a server bug (I'm using prosody 0.9.4) but it would be good if jackline notified the user that the server sent the error reply.

https://xmpp.org/rfcs/rfc3921.html#int-remove for reference

Still fails with prosody 0.9.7. BTW, this is what pidgin sends:

(19:36:12) jabber: Sending (ssl) ([email protected]/main-laptop): <iq type='set' id='purple9ed7e6c0'><query xmlns='jabber:iq:roster'><item jid='[email protected]' subscription='remove'/></query></iq>
(19:36:12) jabber: Recv (ssl)(203): <iq id='purple9ed7e6c0' type='result' to='[email protected]/main-laptop'/><iq id='lx13' type='set'><query ver='457' xmlns='jabber:iq:roster'><item jid='[email protected]' subscription='remove'/></query></iq>

and it works. Probably you should set id= on the iq stanza. Looks like the difference is that you have an empty xmlns='' in the item stanza and that's probably what messes things up for prosody.

thanks for your investigation. I should fix the error reporting soon, removing the xmlns='' will take some more time (I plan to switch the underlying xml library). please bear with me, this is my spare time project.

the error is now reported in the user interface... will leave this open until I fix the actual issue (get /remove working with prosody)
