I am cross-posting in http://support.silisoftware.com/phpBB3/viewtopic.php?f=2&t=255&p=806 but i will update both sides if an answer comes through.
i use capistrano to deploy to my server. so there is symlink involved.
both development machine and server uses ubuntu 10.04
code is exactly the same on both, but development machine had no problems whereas server has a problem.
this is a list of packages of php for my server
dpkg -l | grep php
ii libapache2-mod-php5 5.3.2-1ubuntu4.5 server-side, HTML-embedded scripting languag
ii php5 5.3.2-1ubuntu4.5 server-side, HTML-embedded scripting languag
ii php5-cli 5.3.2-1ubuntu4.5 command-line interpreter for the php5 script
ii php5-common 5.3.2-1ubuntu4.5 Common files for packages built from the php
ii php5-curl 5.3.2-1ubuntu4.5 CURL module for php5
ii php5-gd 5.3.2-1ubuntu4.5 GD module for php5
ii php5-imagick 2.1.1RC1-1build3 ImageMagick module for php5
ii php5-mcrypt 5.3.2-0ubuntu1 MCrypt module for php5
ii php5-mysql 5.3.2-1ubuntu4.5 MySQL module for php5
ii phpmyadmin 4:3.3.2-1 MySQL web administration tool

the solution is to set phpthumb.class.php line 142
var $config_allow_src_above_docroot = true;
this is probably due to the capistrano using symlink but cannot be sure.
