I am running tunnel.py on gnuradio 3.3.0 . It run successfully for a while but after a period of time (around an hour) the following exception prints out:

Rx: ok = True  len(payload) =   82
Tx: len(payload) =   82
Exception in thread Thread-1:
Traceback (most recent call last):
  File "/usr/lib64/python2.6/threading.py", line 525, in __bootstrap_inner
  File "/usr/local/lib64/python2.6/site-packages/gnuradio/blks2impl/pkt.py", line 162, in run
    ok, payload = packet_utils.unmake_packet(msg.to_string(), int(msg.arg1()))
  File "/usr/local/lib64/python2.6/site-packages/gnuradio/packet_utils.py", line 183, in unmake_packet
    payload_with_crc = dewhiten(whitened_payload_with_crc, whitener_offset)
  File "/usr/local/lib64/python2.6/site-packages/gnuradio/packet_utils.py", line 95, in dewhiten
    return whiten(s, o)        # self inverse
  File "/usr/local/lib64/python2.6/site-packages/gnuradio/packet_utils.py", line 91, in whiten
    z = sa ^ random_mask_vec8[o:len(sa)+o]
ValueError: shape mismatch: objects cannot be broadcast to a single shape

After this exception the receive chain seems to stop working. I am still able to transmit but no receive packets are recorded.

Anyone have any clue what could be causing this issue?
