Great, thanks!  Can you please post a backtrace?

The easiest way is:

  $ ulimit -c unlimited
  $ qemu-system-x86_64 -enable-kvm -m 1024 ...
  ...crash...
  $ gdb -c qemu-system-x86_64.core
  (gdb) bt

Depending on how your system is configured the core file might have a
different filename but there should be a file name *core* the current
working directory after the crash.

The backtrace will make it possible to find out where the crash
occurred.

Thanks,
Stefan
