If they segfault, it's because there is a memory problem somewhere.
You can try to debug them with gdb. duma is better because gdb will
point you to the line in cause.

I'm updating my Archlinux to libX11-1.4.0 and I'll see if I can
reproduce the bug.

Another test you can do is to compile xbindkeys with disabled fork.
