[Discuss-gnuradio] uhd_fft.py erroring out today

[Marcus D. Leech]

After pull of latest Gnu Radio code, I'm having a problem with 
uhd_fft.py, but only for USRP2.  It works fine for USRP1:

Traceback (most recent call last):
  File "/usr/local/bin/uhd_fft.py", line 286, in <module>
    main ()
  File "/usr/local/bin/uhd_fft.py", line 282, in main
    app = stdgui2.stdapp(app_top_block, "UHD FFT", nstatus=1)
  File

    self.top_block = top_block_maker (frame, self, vbox, sys.argv)
  File "/usr/local/bin/uhd_fft.py", line 143, in __init__
    self.myform['samprate'].set_value(self.u.get_samp_rate())
KeyError: 'samprate'



I don't even need to explicitly specify a sample rate for this to 
happen, and it only happens on USRP2.

For example, this produces the above error:

uhd_fft.py --args "addr=192.168.10.2"


A uhd_usrp_probe works fine against the device
