Environment:
MariaDB-10.0.16
Galera-3-25.3.9

This statement does nasty things to a MariaDB+Galera cluster:

CREATE TABLE u91rw_zoo_version (`version` varchar(255) NOT NULL) 
                               ENGINE=innoDB DEFAULT CHARSET=utf8
                               SELECT '3.3.3' as version;

Statement fails to replicate to the other nodes because the target
table doesn't exist. Cluster then disassembles itself.

This patch makes the problem disappear. Please evaluate?
(note: patch based against github.com/MariaDB/server.git)

We have a full environment setup in which to test. debug/trace available
on request. Will open bug if required for your workflow.

Thanks,
