[Typo3] Saving the Tutorial Extension fails

[Markus Giesen]

Hello.

I got the tutorial "Creating a basic extension" in front of me.
(http://typo3.org/documentation/document-library/player_profile_basic/)
I tried to save the Extension, but I get the following error:


/** snip **/
Warning: array_merge() [function.array-merge]: Argument #1 is not an 
array in 
C:\typo3_xampp\xampp\htdocs\typo38_qs_learning\typo3\ext\kickstarter\class.tx_kickstarter_sectionbase.php 
on line 700

Can you give me a hand?
