Cannot set Breakpoints in asm

Hi,
I built the 6.8.1 on ubuntu 11.04, and it works  good with c c++ but 
when I start a program built with nasm I get an empty list of function 
and the dash in the listing do not allow to set breakpoints.
I get only the assembler windows working , while the other seems not 
good. I get an empty list of function in the menu selecting the asm 
file. and no function to disassemble in the upper part.

Any idea?

Thanks
