Details:

There is a bug in mqtt_example.c in the function mqtt_example_init. If we call
first mqtt_set_inpub_callback and then mqtt_client_connect,
mqtt_client_connect zeroed client and everything done in
mqtt_set_inpub_callback is reset (making the call useless).

This even leads to a hard fault in mqtt_message_received because
client->data_cb is called without a check.
