Re: [Discuss-gnuradio] uhd_fft.py returns Segmentation fault

[sdoering]

Hello,

just realized that I forgot to insert the part after "bt" 
last time...

So once again:

This is what GDB says:

I definitely have the latest GNURadio release installed.

uhd_find_devices and uhd_usrp-probe both work fine.
