Richard, Straight to the point.
There are a few ways to get out of this problem, most of them driving you to a MySQL DLL downgrade. IMHO, the fact is MySQL 5.1 doesn't work properly with RoR, so, stick with 5.0, report the problem to MySQL staff and wait for: an official patch for 5.1, or for the 5.2 hoping it will solve the problem. That is it.
