TYPO3 Core

I'm testing TYPO3 4.3.0alpha1 at some develop installation, and have stumbled upon some weird behavior with htmlArea and DAM 1.1.1. The error don't occur on installations without DAM.

If I insert a picture in the editor and load the page with the content element in the frontend, I get the following error.

Catchable fatal error: Argument 2 passed to tslib_cObj::isClassAvailable() must be an array, null given, called in /var/www/html/typo3_src-4.3.0alpha1/typo3/sysext/cms/tslib/class.tslib_content.php on line 5989 and defined in /var/www/html/typo3_src-4.3.0alpha1/typo3/sysext/cms/tslib/class.tslib_content.php on line 6417

As far as I understand is "isClassAvailable" a new functionality in TYPO3 4.3, and I suppose in this case "protected function isClassAvailable($className, array $config)" returns a $className with an array $config = NULL, which isn't expected in line 5989, and therefore throws an error.
