Gajim does not (visibly) detect disconnect sometimes with XEP-0198 active
Bug description
When XEP-0198 is in use, sometimes Gajim will appear to be connected when it really has no connection.
XML console usually has an unanswered <r> as one of the last things sent, and no further <r> or XMPP ping is being sent.
Manual reconnection is required to restore everything.
Steps to reproduce
Currently unknown - so far it has only happened while I am away from my computer. It could also possibly be triggered by a certain pattern of network disconnects? These are just guesses.
