xtrabackup / drizzlebackup.innobase is not passing tests

[Patrick Crews]

When trying the xtrabackup file (plugin/innobase/xtrabackup/drizzlebackup.innobase), I am seeing tests fail, particularly in this way:

For this call to the program:
drizzle_xbtest/plugin/innobase/xtrabackup/drizzlebackup.innobase --backup --defaults-file=drizzle_xbtest/tests/kewpie/workdir/bot0/var_s0/drizzled.cnf --datadir=drizzle_xbtest/tests/kewpie/workdir/bot0/var_s0/master-data --target-dir=drizzle_xbtest/tests/kewpie/workdir/bot0/var_s0/_xtrabackup

I see this error:
20120326-210322 Traceback (most recent call last):

20120326-210322 Aborted

Without the default file argument (and with 0 args), I get
