Hi,
I was trying to do a simple relate according to SqlSoup documentation,
but this error keeps popping every time for every tables I try to
relate even though the foreign keys are right and valid and a manual
SQL join works normally:

My Foreign keys are all correctly setup and as a simple relation this
should just work, but I have no idea on what is going on with this.
Anybody had the same issue ?
Follows a description of my environment and the related tables:
OS: Tested on both Linux Ubuntu Natty 64bit and Mac OS X 10.7.1 Lion.
Python: Python 3.2.1
SQLAlchemy: 0.7.2
MySQL: 5.5.12
MySQL Python Driver/Connector: OurSQL 0.9.2
Follows the tables description:
=== audits ===
CREATE TABLE `audits` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`site` varchar(45) CHARACTER SET latin1 DEFAULT NULL,
`zeit` datetime NOT NULL COMMENT 'date the audit was started (zeit =
german for time)',
`responsible` varchar(100) CHARACTER SET latin1 NOT NULL,
`prologue` text CHARACTER SET latin1 COMMENT 'digest at the
beginning',
`checklists` varchar(30) DEFAULT ' ',
`utype` varchar(45) DEFAULT NULL,
`customers_id` int(10) unsigned NOT NULL,
`users_id` int(10) unsigned NOT NULL,
PRIMARY KEY (`id`),
