Thank you for the quick reply yesterday, I got to try the new patched version today,

The latest userspae code is currently at git://git.kernel.org/pub/scm/fs/xfs/xfsprogs-dev.git
The patch I sent applies on top of that, it's not yet been committed to the repo.
The patch as sent should get you through your segfault, but we'll probably end
up merging something a bit different.
