I hit a race with those tests when running master. That's because the s5b-connection-lost event is fired *before* FileTransferStateChanged.

got event:
- type dbus-signal
- args: [3L, 0L]
- interface: 'org.freedesktop.Telepathy.Channel.Type.FileTransfer'
- path: '/org/freedesktop/Telepathy/Connection/gabble/jabber/test_40localhost_2fResource/FileTransferChannel/0xff1df0'
- signal: 'FileTransferStateChanged'
handled

got event:
- type s5b-data-received
- data: 'What a nice file'
- transport: <<class 'twisted.internet.tcp.Client'> to (u'169.254.6.140', 43932) at 2d4e850>
handled

got event:
- type s5b-connection-lost
- connector: <twisted.internet.tcp.Connector instance at 0x2d60368>
- reason: <twisted.python.failure.Failure <class 'twisted.internet.error.ConnectionDone'>>
not handled

got event:
- type dbus-signal
- args: [16L]
- interface: 'org.freedesktop.Telepathy.Channel.Type.FileTransfer'
- path: '/org/freedesktop/Telepathy/Connection/gabble/jabber/test_40localhost_2fResource/FileTransferChannel/0xff1df0'
- signal: 'TransferredBytesChanged'
handled

got event:
- type dbus-signal
- args: [4L, 0L]
- interface: 'org.freedesktop.Telepathy.Channel.Type.FileTransfer'
- path: '/org/freedesktop/Telepathy/Connection/gabble/jabber/test_40localhost_2fResource/FileTransferChannel/0xff1df0'
- signal: 'FileTransferStateChanged'
handled

timeout
still expecting:
 - EventPattern('s5b-connection-lost', **{'predicate': <function <lambda> at 0x2d586e0>})
