[Discuss-gnuradio] Problem with error_rate block?

I was trying to use the error_rate block tonight, and noticed it seems to

be throwing an error related to blocks.message_from_string.  The

following change to error_rate.py seems to have fixed the issue:

diff error_rate.py error_rate.py-orig 

116c116

<         msg = gr.message_from_string(arr.tostring(), 0, gr.sizeof_float, num)

---

>         msg = blocks.message_from_string(arr.tostring(), 0, gr.sizeof_float, num)

139c139

<         msg = gr.message_from_string(arr.tostring(), 0, gr.sizeof_float, num)

---

>         msg = blocks.message_from_string(arr.tostring(), 0, gr.sizeof_float, num)

Just passing this along, if anyone runs into the same problem.
