[Discuss-gnuradio] segmentation fault (core dump) -- help needed

Hi all,
I'm a newbie in gnu software radio (and
in python, and in linux) and got stuck on this segmentation fault issue.
I am trying to setup GNU software radio
on a machine (HP workstation xw8600 with dual intel Xeon processor).
I installed Fedora Core 14 and installed
all needed dependencies using YUM as shown below.
The installation went ok without any
issue.
However, when I tried dial tone example
at "/usr/share/gnuradio/examples/audio/dial_tone.py", it said
nothing else but "segmentation fault(core dump)", and nothing
happened. I tried other examples, but this segmentation fault error came
up all the time. I found a couple of simple gnu radio examples from google
and tried, but the same thing happened. I inserted print statement in the
code to see where it failed and it failed in "my_top_block().run()"
function.
I want to know why this problem occurs
and how to solve it. Can anyone help me out? Any idea/suggestion will be
welcomed.
I'm still studying GNU software radio
blocks, but is there any way to narrow down which block (or which function)
cause this segmentation fault?
