[Discuss-gnuradio] uhd_fft.py returns Segmentation fault

[doering.bas]

Hello list,

I tried to launch the "uhd_fft.py" script with the 
following command line:

"uhd_fft.py -a type=usrp2 -f 935M -s 2M"


My problem is that my terminal always returns this output:

linux; GNU C++ version 4.5.2; Boost_104200; 
UHD_003.001.000-a7927ae

-- Opening a USRP2/N-Series device...
-- Current recv frame size: 1472 bytes
-- Current send frame size: 1472 bytes
-- mboard0 is MIMO master
Segmentation fault


I am using Linux Ubuntu 11.10, 32bit, Intel® Core™2 Duo 
CPU P8600 @ 2.40GHz × 2, USRP N210 with WBX.
I also use ClockTamer as reference for the internal XO and 
2 normal GSM 900 antennas.

I would really appreciate if someone has an idea on what I 
am doing wrong here.

Thanks in advance!

Sebastian
