When trying to create a new "News Category" record in the list module, the following Exception is thrown:

#1: PHP Catchable Fatal Error: Argument 1 passed to TYPO3\CMS\Backend\Tree\AbstractTree::setNodeRenderer() must be an instance of
t3lib_tree_renderer_Abstract, instance of TYPO3\CMS\Core\Tree\TableConfiguration\ExtJsArrayTreeRenderer given, called in
C:\xampp\htdocs\currenttruk\typo3\sysext\backend\Classes\Form\Element\TreeElement.php on line 91 and defined in
C:\xampp\htdocs\currenttrunk\typo3\sysext\backend\Classes\Tree\AbstractTree.php line 7

This happens with current TYPO3-Core from Git (6.0-dev) and current Git-Version from tx_news (but seems to be a bug in the core, since the extension only tries to use a field-type from TCA).

Note, this appears to happen because t3lib_tree_renderer_Abstract is no longer part of the inheritance tree for \TYPO3\CMS\Backend\Tree\AbstractTree.

It will no longer be possible to check for implementations of parent classes and interfaces (in a way that works equally on pre-6.0 and 6.0). Sorry guys.

this is indeed bug in core
TYPO3\CMS\Backend\Tree\AbstractTree::setNodeRenderer [1]
is defined as:
public function setNodeRenderer(\t3lib_tree_renderer_Abstract $nodeRenderer) {

but it should use namespaced class name
