Just for fun I tried "dbus-ifying" the dictionary entirely before handing it to telepathy. That is, instead of a dict, I created a dbus.Dictionary, with signature 'sv', with dbus.String keys and dbus.String values. Unsurprisingly, this had no effect. Tried it again with Salut. Same result. Changing component to telepathy-python, seeing as neither Gabble nor Salut seems to pass along the parameters through ListTubes. OK. I figured out what I was doing wrong. I was following the argument spec from http://telepathy.freedesktop.org/spec/org.freedesktop.Telepathy.Channel.Type.StreamTube.DRAFT.html#org.freedesktop.Telepathy.Channel.Type.StreamTube.DRAFT.OfferStreamTube but actually, the function I was calling was http://telepathy.freedesktop.org/spec/org.freedesktop.Telepathy.Channel.Type.Tubes.html#org.freedesktop.Telepathy.Channel.Type.Tubes.OfferStreamTube Now it's working. So this is not a bug, at least not in the code. The spec could be a bit clearer... |

When using OfferStreamTube in one Sugar Activity, I set the Parameters argument to be a python dict with strings as keys and strings or ints as values. I then connected a callback function to NewTube, and also called ListTubes with a reply callback function. The Tube was apparently already available, so ListTubes replied with a non-empty list of tubes. The list contained a single element (tube_info), whose params component was an empty dict: the debug trace shows dbus.Dictionary({}, signature=dbus.Signature('sv')). This makes me suspect that the parameters dictionary is not hooked up correctly in ListTubes. I am running OLPC OS builds 767 and 801. (i.e. 8.2 and 8.2.1). I am not sure what Telepathy versions are present here. Telepathy-gabble was in use, accessed via telepathy-python.
