I updated the database schema for a custom model and run the install tool. After that, I'll be promted with a white screen, finding the following error in the log file: \r\n\r\n[15-Jan-2015 11:55:49 GMT] PHP Fatal error:  Class 'Database\\' not found in ...\\system\\modules\\core\\library\\Contao\\Database.php on line 160\r\n\r\nContao Check says, everythings fine. I deactivated all custom modules. \r\n\r\nI don't know, why the install tool crashes (the database scheme is updated according to my previous changes in the DCA), but I found out that #7412 is the same issue and the following suggestion of @leofeyer solves my proplem: https://github.com/contao/core/issues/7412#issuecomment-63320741\r\n\r\nDid somebody else already experience this issue in 3.2.16?"}}
