If you select a leaf element of the Help Contents tree and you press the RIGHT key an error window pops up:

   A Runtime Error has occurred.
   Do you wish to Debug?
   Line: 252
   Error: 'parentNode' ist Null oder kein Objekt

In English it means: 'parentNode' is Null or no Object

Having a look to the debug possibilities I ended at:

/help/advanced/helptree.js

The run pointer points to the first line of:

function makeVisible(treeItem) {
    var parent = getTreeItem(treeItem.parentNode); // <---



Reproducible: Always

Steps to Reproduce:
1. Open Eclipse Help (Help -> Help Contents)
2. From the Contents tree select a leaf (e.g. "Eclipse platform overview" which is a child of the top level element "Workbench User Guide)
3. Press the RIGHT key. This is normally used to open the childs of a parent element.
