I'd recommend installing the empathy debugging symbols (empathy-dbgsym
or empathy-dbg) and launching empathy under gdb. (Try sending a bt
full, perhaps empathy needs a bit more defensively coding).

The full clients like empathy & ktp-contactlist expect several
interfaces to be available and you may not have implemented everything
yet.

When I was trying to write a CM I found the example roster in
TelepathyQt/examples/roster doesn't expect as many interfaces to exist
and I was able to get it to work before empathy or KTP did.

I believe the handles being negotiated between the client and the CM
are a pointer like type so you can refer to large contact objects by
reference.
