I wasn't able to repeat on Linux Debian with today BK source,
so it is an issue already fixed:
miguel@hegel:~/dbs/5.0$ bin/mysqladmin -uroot create dbbug
miguel@hegel:~/dbs/5.0$ bin/mysql -uroot dbbug
Welcome to the MySQL monitor. Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

Thank you for your bug report. This issue has already been fixed in the latest released version of that product, which you can download at http://www.mysql.com/downloads/
Description: mysqldump omits closing quote on generated insert statements when the content of any text type field contains a solitary double quote. This makes restoring data containing such instances extremely difficult. How to repeat: Create a table with a char/varchar/XXXtext field and insert one double quote ("). Mysqldump will generate an insert statement containing an opening single quote, but omitting the double quote contained in the field and the closing single quote. mysql> create table bugtable (charField char(10), varcharField varchar(10), tinytextField tinytext, textField text, mediumtextField mediumtext, longtextField longtext); Query OK, 0 rows affected (0.01 sec) mysql> insert into bugtable (charField, varcharField, tinytextField, textField, mediumtextField, longtextField) values ('\"','\"','\"','\"','\"','\"'); Query OK, 1 row affected (0.00 sec) mysql> select * from bugtable \G *************************** 1. row *************************** charField: " varcharField: " tinytextField: " textField: " mediumtextField: " longtextField: " 1 row in set (0.00 sec) mysql> quit Bye <289 dbm:~>mysqldump -u xxx -pxxx bug; -- MySQL dump 10.10 -- -- Host: localhost Database: bug -- ------------------------------------------------------ -- Server version 5.0.4-beta-max-log /*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */; /*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */; /*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */; /*!40101 SET NAMES utf8 */; /*!40014 SET @OLD_UNIQUE_CHECKS=@@UNIQUE_CHECKS, UNIQUE_CHECKS=0 */; /*!40014 SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=0 */; /*!40101 SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='NO_AUTO_VALUE_ON_ZERO' */; /*!40111 SET @OLD_SQL_NOTES=@@SQL_NOTES, SQL_NOTES=0 */; -- -- Table structure for table `bugtable` -- DROP TABLE IF EXISTS `bugtable`; CREATE TABLE `bugtable` ( `charField` char(10) default NULL, `varcharField` varchar(10) default NULL, `tinytextField` tinytext, `textField` text, `mediumtextField` mediumtext, `longtextField` longtext ) ENGINE=MyISAM DEFAULT CHARSET=latin1; -- -- Dumping data for table `bugtable` -- /*!40000 ALTER TABLE `bugtable` DISABLE KEYS */; LOCK TABLES `bugtable` WRITE; INSERT INTO `bugtable` VALUES (',',',',','); UNLOCK TABLES; /*!40000 ALTER TABLE `bugtable` ENABLE KEYS */; /*!40101 SET SQL_MODE=@OLD_SQL_MODE */; /*!40014 SET FOREIGN_KEY_CHECKS=@OLD_FOREIGN_KEY_CHECKS */; /*!40014 SET UNIQUE_CHECKS=@OLD_UNIQUE_CHECKS */; /*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */; /*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */; /*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */; /*!40111 SET SQL_NOTES=@OLD_SQL_NOTES */; Suggested fix: Correct quote escaping algorithm.
