[horde] php upgrade problem

[fixinko@localnet.sk]

Hello, I noticed a problem after upgrade of php 5.0.5 to php 5.1.0. While trying
to open INBOX horde/imp, I get an error message saying "Cannot use object of
tybe DB_mysql as array in /services/www/html/html/horde/lib/Horde/DataTree.php
on line 590". I'm using apache 2.0.55, mysql 5.0.15, horde 3.0.7, imp H3 4.0.4.
How to fix this problem? Thanks

fixinko
