[Papyon] Issue with switchboards

[Riccardo (C10uD)]

In emesene2 we're using msnp18, and sometimes i personally experienced
the following issue:
i leave a conversation opened and after some time it's like dead. but
it doesn't tell anything about missing messages or anything. i see
another user found the issue [1].
i was wondering if we should manually handle the conversation.leave()
after a given amount of time, or papyon should tackle that
automagically. or the other party is using a crappy client that
doesn't do X and breaks our switchboards.
How about it? did you ever see such issue? Ideas?
