Module ItemAdd doesn't upload

Hi all,
I have recently upgraded from 2.3 to 2.3.1 and now module ItemAdd doesn't upload anything.
Files and dirs permissions are ok but it seems it doesn't find any file.

Gallery version: 2.3.1 core 1.3.0.1
API = Core 7.54, Module 3.9, Theme 2.6, Embed 1.5
PHP version: 5.2.6-1+lenny4 apache2handler
PHPInfo Link (see FAQ):
