@Justin,
Since it is crashing with segfault, can you enable core-dumps and provide a backtrace from it?
gdb `which xtrabackup_51` --core <core-file> --batch --quiet -ex "thread apply all bt full" -ex "quit"
IS this Xtrabackup built from source or installed from Percona RPM?
If latter, then make sure you have percona-xtrabackup debug package installed as well before producing the core.
