[TYPO3-dev] Fatal error with backend and install tool in TYPO3 6.1.7

[Franz Holzinger]

Hello,

when I upgrade a perfectly running TYPO3 6.1.5 up to TYPO3 6.1.7 then 
both the TYPO3 backend and the TYPO3 Install are gone. Only this error 
message is shown:

Fatal error: Class 'tx_div2007_core' not found in 
/var/www/userpath/typo3conf/ext/tsparser/ext_localconf.php on line 10

This line is here:
----------
if (
	TYPO3_MODE == 'BE' &&
	t3lib_extMgm::isLoaded('div2007')
) {
	$typoVersion = tx_div2007_core::getTypoVersion();  <======
-----------------

If I go back to TYPO3 6.1.5 then everything works fine again.
