Martin,
Unfortunately, I'm unable to provide any insight. SInce I have not experienced the error you report.
I run WinXP with KT on two machines in my office (one with 2.0.7 and one with 3.0.1). The php/sql environemnt is EasyPHP (Apache 1.3.33, PHP 4.3.10, Mysql 4.1.9).
The host server is Linux with Apache 1.3.34, PHP 4.4.2, Mysql 4.4.14
If you want to have a look at the public KT app' (2.0.7) follow the link http://www.wfassociates.com.au and click on the KnowledgeTree icon. The guest login is 'guest' password 'guest'. There are some documents you can look at, just browse around.
This may not help, but will at least provide you with some confidence that KT works ok.
