Including DatabaseUtility fails due to Null Character
(This one is strange and it took me a while to figure it out)
In typo3/sysext/extensionmanager/Classes/Utility/DatabaseUtility.php line 129, position 38 there seems to be a so called Null Character1 which raises an error when the file is included. In my case the whole PHP process seems to be killed - the browser receives no response from the server. This way the EM and the Language module fail to load.
I found the problem via Command Line:
$ php -l DatabaseUtility.php
Bus error: 10
When I erase the Null character everything works fine.
Attention: I'm experiencing this on a Mac with Intel chip. This smells system dependant to me.
(I can't even provide a patch because git seems to handle DatabaseUtility.php as a binary file because of the Null character)
