Looking at base-client.c:2336: 2332 channel = ensure_channel (self, connection, chan_path, chan_props, 2333 &error); 2334 if (channel == NULL) 2335 { 2336 → DEBUG ("Failed to create TpChannel: %s", error->message); 2337 goto out; 2338 } This plus: SegvReason: reading NULL VMA suggests to me that 'error' is NULL, which suggests to me that 'ensure_channel' (or rather, something within it) is hitting g_return_if_fail(). From the .xsession-errors file, a few instances of: (empathy:26326): empathy-CRITICAL **: empathy_contact_get_account: assertion `EMPATHY_IS_CONTACT (contact)' failed are the only criticals I see. From ProcStatus.txt: Pid: 28326 Soooooooo this looks like Empathy is probably at fault here.
