Yes, -g3 is fine and preserves more information but it may still trigger
a bug in gdb sometimes because it is not the default setting.

Yes, --exec-on-crash is explained here:
http://sourceforge.net/mailarchive/message.php?msg_id=37504000

With --pause-on-crash the process is simply suspended when a crash occurs.
You can then attach with gdb to the process and inspect it as usual:

$ gdb /path/to/gtk-gnutella <pid>
