It looks like the error string set by g_dbus_get_finish() is pointing to
garbage. This is possibly an issue for upstream glib?
Here's the code where the error occurred:
/* Callback for getting our connection to DBus */
static void
bus_get_cb (GObject * object, GAsyncResult * res, gpointer user_data)
{
GError * error = NULL;
GDBusConnection * connection = g_bus_get_finish(res, &error);
if (error != NULL) {
g_error("OMG! Unable to get a connection to DBus: %s",
error->message);
g_error_free(error);
return;
}
And here's the backtrace, notice that args1 (which would be the
error->message string for %s) is garbage:
