Program terminated with signal SIGTRAP

Hi, I'm faily new to dgb but I have the basics. I'm trying to debug a  
segfault on a multi-threaded application (helix-client), but gdb  
isn't happy. This is what happens when I run it:

---

Program terminated with signal SIGTRAP, Trace/breakpoint trap.
The program no longer exists.

as far as I can tell, this is something to do with threading... heres  
a little info about my setup::

gdb:                    6.4, compiled with:

--disable-gdbtk --disable-tui --disable-x \
--with-curses --disable-multilib --with-readline --disable-sim \
--program-prefix=''"

glibc:                   2.4
gcc:                     3.4.4
libthread-db1:   2.4
libc6:                   2.4

can anyone provide a little insight as to what might be going on here  
and what I can do to fix it?

many thanks
tom
