Can anyone explain this behaviour ?
mysql> select version();
+--------------+
| version() |

1 row in set (0.00 sec)
mysql> create database foo;
Query OK, 1 row affected (0.01 sec)
mysql> use foo;
Database changed
mysql> CREATE TABLE test (
id bigint(20) NOT NULL AUTO_INCREMENT,
stuff varchar(10) DEFAULT NULL,
PRIMARY KEY (id)
) ENGINE=InnoDB;
Query OK, 0 rows affected (0.04 sec)
mysql> SHOW CREATE TABLE test \G

We have found a workaround (sort of):
mysql> DROP TABLE test;
Query OK, 0 rows affected (0.04 sec)
mysql> CREATE TABLE test (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
stuff varchar(10) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB;
Query OK, 0 rows affected (0.10 sec)
mysql> INSERT INTO test (id, stuff) VALUES (-1,'Hello!');
Query OK, 1 row affected (0.03 sec)
mysql> SHOW CREATE TABLE test \G
*************************** 1. row ***************************
Table: test
Create Table: CREATE TABLE `test` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`stuff` varchar(10) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1
1 row in set (0.00 sec)
mysql> INSERT INTO test (id, stuff) VALUES (0,'Hello!');
Query OK, 1 row affected (0.03 sec)
mysql> SELECT * FROM test;
+----+--------+
| id | stuff |
+----+--------+
| -1 | Hello! |
| 1 | Hello! |
+----+--------+
2 rows in set (0.00 sec)
For those that missed it, the difference is the backticks in the CREATE TABLE line.
Also I've yet to test with other versions.
Update
Looks like this is a bug that was fixed in 5-1-31
