Please review HR fix for issue 
https://netbeans.org/bugzilla/show_bug.cgi?id=235442

The problem is caused by some debugging code that wasn't removed before 
the commit. Because of that a HTML Preview tab shows in every HTML 
document window and NullPointerException may be thrown when closing that 
document window.

The fix is safe as it just deactivates a piece of code that isn't 
supposed to be available in NetBeans 7.4
