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
[Thread debugging using libthread_db enabled]
linux; GNU C++ version 4.5.2; Boost_104200; 
UHD_003.001.000-a7927ae

Program received signal SIGSEGV, Segmentation fault.
0xb6fdf26f in boost::thread::start_thread() () from

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