Hello Josh,

thanks for your answer.

I have run the programm once again using gdb and the 
output is:

----------------------------------------------------------------------------------------------
Starting program: /usr/bin/python uhd_fft.py -a type=usrp2 
-f 935M -s 2M

I just used the version that was online Thursday last 
week. I think this one is up to date... (?)
