Uhd_fft.py erroring out today

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):

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
