PXC uses innobackupex, but the SST fails with the same error:
2014-10-02 04:02:02 7f60b6b33720 InnoDB: Operating system error number 13 in a file operation.
If found this bug when debugging why SST wasn't working. I had to run the SST process manually with strace to finally find the problem. So most probably, that implementation that reads the datadir from the server connection doesn't work in all cases.
