Heres a fun one, it's impossible to get the Zend IDE/Debugger working with current Ubuntu releases because they've added the suhosin patch to the PHP binary, I've tried a few things..

- It was said that the suhosin stuff appears in only the php5-suhosin package, but even without this installed, It was still getting in the way somehow, theres a ubuntu launchpad bug for this https://bugs.launchpad.net/ubuntu/+source/php5/+bug/498022

Zend IDE mysteriously stopped debugging, firefox toolbar just would not start the debugger and always said Zend was not detected no matter what i done, turns out, it was listening on ipv6 ports

"Zend Debugger requires Zend Engine API version 220060519."

From what i've gathered, looks like Zend dont fully support the latest php 5.3, so downgrade unfortunately is the answer!

That's it, I quit, I'm throwing
