Comment 1 Will Thompson 2011-10-14 05:44:04 UTC 
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.

If this is still an issue nowadays, please report to Empathy.
