MSN for Mac client invisible when comes online

Binary package hint: telepathy-butterfly

Reporting this as a new bug as advised in bug 489647.

Whenever my friend connects to MSN via his MSN Messenger for Mac Client (version 8.0.0 (100305) beta). He does not show up in my available contacts list.

Other clients appear fine (including Adium).

Nothing appears in the empathy logs.

In the butterfly log, when he connects, the following appears:
