fighting-layout-bugs crash at runtime

Whenever I try to run fighting Layout bugs on a specific page of a portal under 
development (not visible from the Internet) I get following Error. 
(On other pages I do not have any issue - it is just on a specific one)

What version of the product are you using? On what operating system?
I use the latest version with all dependencies. 
(fighting-layout-bugs-0.5-jar-with-dependencies.jar)
Running on : 
System info: os.name: 'Windows XP', os.arch: 'x86', os.version: '5.1', 
java.version: '1.6.0_20'
(From a jUnitTest from inside Eclipse)
