Hi,

as I said before (but I don't know whether it came through because of the
mail hickups), the problem in gdb is almost certainly caused by xinetd 
that is still running and listening to port 6566. xinetd has to be stopped
first before running saned in gdb:

   /etc/rc.d/init.d/xinetd stop
   
After that, it should be possible to get a stack trace of the point where
saned hangs.
