A bit of googling takes you to
https://bugs.launchpad.net/ubuntu/+source/qemu-linaro/+bug/758424.
Key quote:

"We only implement the futex syscalls if CONFIG_USE_NPTL. This isn't
defined for the i386 target (the necessary support in target-i386 for
pushing atomic insns up to the linux-user top level loop isn't
implemented). The upshot is that running multithreaded programs in
linux-user i386-target isn't supported and this is just one of the
symptoms."

Not segfaulting != working when multithreaded programs don't have
futexs.  We'll be seeing this more in the future now that GLib assumes
you can thread.
