[TYPO3-dev] Extension manager error at 6.0.8

[Sven Hofacker]

Hi there,

after pressing the update button in the extension manager, i get the
following error:
{"updated":false,"lastUpdateTime":"20:47:03 pm07
05.07.2013","timeSinceLastUpdate":"26 Tage","errorMessage":""}

and if i try to install an extension, then the following error will be
shown:

#1294585070: No module "" could be found. (More information
<http://typo3.org/go/exception/CMS/debug/1294585070> )

UnexpectedValueException thrown in file
/var/www/vhosts/ho-it.pw/leasing/typo3/mod.php in line 55.


Is this a bug?
what can i do to fix this problem?
