[Discuss-gnuradio] ValueError: operands could not be broadcast together with shapes (4095) (4081)

Hi everybody,

I am also facing this problem. I am running a GMSK modulation and sometimes I get the error:

Exception in thread Thread-915:
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 808, in __bootstrap_inner
    self.run()

    ok, payload = packet_utils.unmake_packet(msg.to_string(), int(msg.arg1()))

    payload_with_crc = dewhiten(whitened_payload_with_crc, whitener_offset)

ValueError: operands could not be broadcast together with shapes (4095) (4081)

I really dont know what could be happening. What I have realize is that everytime this happens, even though the code keeps running, the flow does not keep working as is suposed to.

Any idea???
Thanks
