I do not know how to reproduce. Please give details.
FYI I'm using all pending patches (in core-list) for DBAL:

I was not able to reproduce this behaviour neither.
However, it seems that spl_autoload() throws an exception when a class could not be loaded on some systems. I've wrapped the fallback to spl_autoload() with try/catch.
Please test the attached patch and tell me, if DBAL still works on your system. Thanks!

Patch works fine. Thanks!
For Reproducing: I use a Debian Etch Installation with Usermin/Virtualmin Default Configuration.

Ok... I could reproduce this on a live server with
PHP 5.2.0-8+etch13 (cli) (built: Oct 2 2008 08:26:18)
Seems to be a PHP or Debian issue with spl_autoload() - I'm not using DBAL on the mentioned system.

I have the same.
Debian etch, php 5.2.0+dfsg-8+etch15, php running as fastcgi under apache...
Problem arises with alpha3 : alpha2 runs well (at least the start).
a very basic typo3 installation...

Upd: but patch helps - I get the install page... :-)

More infos:
in class.t3lib_div.php we have a function:
protected function getClassName($className) {
return (class_exists($className) && class_exists('ux_' . $className) ? self::getClassName('ux_' . $className) : $className);
}theese two variations work (between the {}):
return $className;
or
return (class_exists($className) && class_exists('ux_' . $className, false) ? self::getClassName('ux_' . $className) : $className);

Hi Christian,
the class_exists() with the second parameter to false might be a valid thing - however, the problem here is related to the exception thrown by spl_autoload() in PHP 5.2.0/Debian.
If an extension would just check for any class by e.g. class_exists('someOtherClass') the same error would occur.
Thus, using try/catch to prevent the LogicException to be thrown is the only way here.
