Created attachment 98062 [details] Bustle log What's currently happening: - App A has a channel. - App A tells MC to delegate a channel to AppB - MC sends sends a HandleChannels call to my AppB with a all the normal stuff and a path to the ChannelDispatcherRequest path as the Requests_Satisfied: @ao ["/org/freedesktop/Telepathy/ChannelDispatcher/Request24"] (this is the same request path as when MC gave App A a HandleChannels) - TpQt does it's introspection and tries to load the request from the ChannelDispatcher - it fails with "GetAll" with signature "s" on interface "org.freedesktop.DBus.Properties" doesn't exist" - TpQt then explodes and ignores the request. From what I can tell there is no request object on MC, as the channel is already handled. I think we should modify _mcd_client_proxy_handle_channels to have some argument to know if it is delegating channels and if so not send any Requests_Satisfied. Am I right? If I modify TpQt to silently ignore loading the ChannelRequest error, everything works perfectly. I've attached a quite simply bustle log of the problem.

I think this is also a TpQt bug, or possibly design flaw (but perhaps one that you can't fix without breaking API, so you might need to fix it in 'next'). In telepathy-glib we deliberately didn't require, or wait for, the ChannelRequest to prepare successfully, because it takes a round-trip and approximately nobody is going to need it. The main purpose of Requests_Satisfied is matching up channels you're being asked to handle with either requests you started (if you create/ensure channels), or channels whose channel request you were previously asked to approve (if you're an Observer or Approver). If you're doing either of those, you have a TpChannelRequest already, it's probably already prepared too, and all you need to do is match it by object path or by object identity, for instance looking it up in a hash table { channel request => chat window }. If you're not doing either of those, HandleChannels seems too late for the channel request to be useful.
