Bug #65571	mysqldbcopy crashes [IndexError: list index out of range]

Description:
I have reproduced this twice once on wamp with mysql 5.1.x and again on 5.1.55-MariaDB running on Gentoo Linux Kernel 3.2.1-gentoo-r2

I ran an extended myisam check on both databases that returned clean.

The last line of output from the command below is:
"# TABLE     search_total                            pass    FAIL   "

Here is the schema for the table:
--
-- Table structure for table `search_total`
--

DROP TABLE IF EXISTS `search_total`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `search_total` (
  `word` varchar(50) NOT NULL DEFAULT '',
  `count` float DEFAULT NULL,
  PRIMARY KEY (`word`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
/*!40101 SET character_set_client = @saved_cs_client */;

How to repeat:
Run mysqldbcompare.exe --server1=root:***@*** --server2=root:***@*** current:prod -a on a database with a table with a varchar key

What exact version of MySQL Workbench (or mysqldbcompare utility) do you use?

For me the following version (from Workbench 5.2.40) works without any problem:

C:\Program Files\MySQL\MySQL Workbench 5.2 CE\utilities>mysqldbcompare --server1
