Imagine that Empathy observes text and streamed-media channels, and Kopete observes text channels only. A NewChannels signal announces a text channel and a streamed-media channel simultaneously; obviously, Empathy gets ObserveChannels called with both channels as arguments. telepathy-spec does not specify whether Kopete's ObserveChannels method is called with the text channel, or with both channels. (In MC 5 it only gets the text channel - i.e. the subset of the bundle that it understands - which seems reasonable.)
I propose to resolve this by accepting MC 5's behaviour. http://git.collabora.co.uk/?p=user/smcv/telepathy-spec-smcv.git;a=shortlog;h=refs/heads/observer
typo in that branch: in the approver/handler part, handler says "approver" Other than that, observer-abibreak approved by discussion among the spec cabal.
Merged (before fixing the typo, oops), will be in 0.17.23; typo fix pending review.
