Description Florent Le Coz 2010-06-08 03:24:02 UTC
A papyon client CREATES a conversation with one contact, then invites one other contact. If the papyon client then leaves (papyon.Conversation.leave()) the conversation, the other clients don't get the "client left the conversation" message, and we are still in the conversation (we still receive the message sent in it).
Then, if both the two client leave the conversation, you get this traceback :


Traceback (most recent call last):

Reproducible: Always

How to reproduce step-by-step, with papyon debug :


* Create a conversation with one contact :
INFO:papyon.protocol.switchboard_manager:requesting new switchboard
INFO:papyon.protocol.switchboard_manager:New switchboard attached

* Invite one other contact in this conversation :

	still there ?

Important note : This bug occurs only if WE (the papyon client) created the conversation. If we are just invited in one conversation, this never happens.
