I upgraded mysql to 5.1.54 using debian experimental packages and the
problem is
gone.
Hopefully it won't break my ubuntu setup, which was a brand new 10.10
using
official packages.

You haven't tried mysql5.1.49 which was specified in squarious'
description.
I just tried with php 5.3.4 stable and mysql5.1.49 without success.
