Fedora might have a better doc but…

(see man 3 backtrace, which is used within X) the easiest way is to
get X to dump a core, or to attach it from gdb (possibly from another
machine); here's the doc I'm pointing Debian users to, instructions
there should be quite portable across distros:
  http://pkg-xorg.alioth.debian.org/howto/use-gdb.html

You may want to post kernel logs (see dmesg), and mention your kernel
and X versions (unless everyone else knows what Fedora 15α ships).
