    What steps will reproduce the problem? 1. Have a MUC component on a prosody server 2. Set up a room 3. Send a disco#info query to that room What is the expected output? <iq id="foo" type="result" to="admin@xmpp.example/gajim" from="test@muc.xmpp.example"> <query xmlns="http://jabber.org/protocol/disco#info"> <!-- ... --> </query> </iq> What do you see instead? <iq id="foo" type="result" to="admin@xmpp.example/gajim" from="test@muc.xmpp.example"> <query xmlns="http://jabber.org/protocol/disco#info" node=""> <!-- ... --> </query> </iq> What version of the product are you using? On what operating system? Prosody 0.11.5 on GNU/Linux Please provide any additional information below. Noticed that Gajim was apparently not properly handling disco#info query responses from MUC's on my service. I checked trunk and it appears to still be present there, as well.

    Thanks for the report! I have noticed this myself from time to time but it never broke anything for me and I didn't investigate further. Does this cause problems in some client? Should be an easy fix in case you would like to try to fix it yourself ;)

    It prevented Gajim from listing the number of occupants my room had, at least. I hadn't noticed any further improper behavior, though. I did give it a shot at fixing, and it seems that it works alright. Haven't done much extensive testing; hopefully, it's trivial enough to not break anything. Patch for trunk: 375c375 < local node = stanza.tags[1].attr.node or ""; --- > local node = stanza.tags[1].attr.node; 380c380 < if node ~= "" then --- > if node and node ~= "" then Patch for 0.11: 339c339 < local node = stanza.tags[1].attr.node or ""; --- > local node = stanza.tags[1].attr.node; 344c344 < if node ~= "" then --- > if node and node ~= "" then

    Thanks, added as https://hg.prosody.im/0.11/rev/552cafd30eb2 In the future, try to use the unified diff format, it is easier to work with.
