Internal Server Error: TypeError "cannot read property 'children' from undefined"

What steps will reproduce the problem?
1. Added javascript-console-0.4.3.jar to tomcat/shared/lib
2. Restart Alfresco
3. Log in to Share, open Javascript console

What is the expected output? What do you see instead?
Expected to get normal console screen with the ability to write and execute 
code. Instead I go to the Javascript Console screen, I get an error prompt 
stating "Internal server error" followed by output on the logs. If I then do a 
basic test; select Repository folder as my Space, and run the code 
"print(space.properties.name);" I get an error message on the Output screen: 

500 

03100004 Wrapped Exception (with status template): Error executing one if the 
included scripts from the data dictionary.
TypeError: Cannot call method "createNode" of undefined 
(jar:file:/C:/Alfresco4/tomcat/shared/lib/javascript-console-0.4.3.jar!/alfresco
/templates/webscripts/de/fme/jsconsole/execute.post.js#252)

What version of the add-on are you using? Please provide version of the
downloaded package, or Subversion revision number.

I get the following output on the logs when I visit the javascript console 
screen:
