Apache::DBI/AutoCommit error

I sometimes get:

DBD driver has not implemented the AutoCommit attribute at
/usr/local/lib/perl5/site_perl/5.8.8/Apache/DBI.pm line 277.

On my HTML::Mason site. I'm using Apache 2.2/mod_perl 2.
I list
PerlModule Apache::DBI
before any other perl modules.

I connect with AutoCommit => 1

What am I doing wrong?
