A warning was emitted (during a butterfly connexion in telepathy) by the galago-daemon (that I launched in a terminal), see the Launchpad bug report https://bugs.launchpad.net/telepathy-python/+bug/106167/ for further details.
Is this reproducible, and can you get any further debug logs? It's likely to have been a bug in either butterfly or telepathy-feed rather than in telepathy-python - telepathy-feed is inspecting handles that butterfly has, for whatever reason, invalidated (e.g. because the contact disappeared, or because for some reason butterfly gave telepathy-feed some invalid handles in response to an earlier call). As I commented on the Launchpad bug, the traceback is to be expected in this situation and does not indicate a bug in telepathy-python.
