While in the process of switching a database server from Percona Server 5.5.28-rel29 (in a master-master relationship) to Percona XtraDB Cluster, I encountered a situation where any attempt to start the slave on the Cluster server would cause a SEGV.
A similar (or possibly identical) crash was reported as part of https://bugs.launchpad.net/galera/+bug/1036774 back in September.
As with the above report, the only way to get past that point in the binlogs was to switch back to the base Percona server version.
We've also seen 4.5 million "WSREP: skipping FK key append" messages, as described in https://bugs.launchpad.net/codership-mysql/+bug/1057910
Here's the dump from the logs. Config file is attached.

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
Please help us make Percona Server better by reporting any
bugs at http://bugs.percona.com/
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1945858 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
