This looks like a libindicate bug

[Launchpad Janitor (janitor)]

This bug was fixed in the package telepathy-indicator - 0.2.1-0ubuntu1

---------------
telepathy-indicator (0.2.1-0ubuntu1) precise; urgency=low

  * New upstream release
    - Bugs fixed:
      * shows my own nick name in chat notifications, not the one of the
        peer (LP: #926072)
      * Use IndicateInterests to determine if there are listeners, this will
        prevent crashers if telepathy-indicator gets run in gnome-shell or
        other environments without a messaging indicator (LP: #947590)
      * Only autostart in Unity and GNOME classic
      * SIGSEGV in g_file_get_path() (LP: #910785)
      * crashed with signal 5 in g_simple_async_result_complete() (LP: #925829)
      * SIGSEGV in handle_contacts_pending_add_indicator_cb() (LP: #929002)

This shouldn't have been referenced in the telepathy-indicator changelog, it is not fixed yet.

Okay, it's definintely crashing in libindicate. The process is in libindicate/server.c's bus_connection_cb() callback func and calls g_bus_get_finish() to complete making the connection. g_bus_get_finish() returns an error, which bus_connection_cb() tries to log. The crash takes place while logging the error, making me think the error message is corrupt.

The code:

    static void
    bus_connection_cb (GObject * obj, GAsyncResult * res, gpointer user_data)
    {
            GError * error = NULL;

            GDBusConnection * connection = g_bus_get_finish(res, &error);
            if (error != NULL) {
                    g_error("Unable to get session bus: %s", error->message);
                    g_error_free(error);
                    return;
            }
