[TYPO3-extbase-kickstarter] extbase_kickstarter, git repository exists ?

[Gianluca Strafella]

Hi guys,
I would work with extbase_kickstarter extension  in TYPO3 4.5.19 and 
i've attempted to download extension it by git 
(git://git.typo3.org/TYPO3v4/Extensions/extbase_kickstarter.git).

When I do:
git clone git://git.typo3.org/TYPO3v4/Extensions/extbase_kickstarter.git

the result is:  fatal: Could not read from remote repository.

Can you help me ?

Thank you in advance,
Gianluca
