Description

I am using telepathy-salut master (57edd8ed) and I am testing with examples/stream_tube_client.py from telepathy-python version 0.15.3.

I am using account files like this: manager: salut protocol: local-xmpp jid: albantest01@example.com first-name: albantest01 last-name: albantest01 published-name: albantest01

How to reproduce:

  1. Start telepathy-salut
  2. In the first console: PYTHONPATH=$PWD/build/lib python ./examples/tube-stream-muc.py ~/salut2.account salle01 --initiator
  3. In the second console: PYTHONPATH=$PWD/build/lib python ./examples/tube-stream-muc.py ~/salut.account salle01
  4. Press Ctrl-C on the second console:

received: hi ! received: hi ! ^CTraceback (most recent call last): File "/home/alban/git/telepathy-python/examples/stream_tube_client.py", line 218, in read_socket data = s.recv(1024) KeyboardInterrupt

  1. telepathy-salut is still alive
  2. Press Ctrl-C on the second console again.
  3. telepathy-salut aborts

It tries to send the result IQ stanza because we finished to use the OOB.
