So help me help you...

What version of gnuradio?
What version of uhd?

Do the uhd example apps work?
Can you import the gnuradio python module?

What about making a quick FFT app in gnuradio companion (uhd usrp source
-> fft sink)? Does that work?

This could be an ABI mismatch, or maybe a bug.
Have you tried updating and rebuilding?
