During installation after "Database Configuration" step, the page goes blank

This issue has been tracked down and the problem is the code "while (($entry = $folder->read()) !== false) {" in the file modules_helper.php, which comes near line 220 (Please check couple of lines above and below). The script quits without informing when a call is made to "$folder->read()", The reason is the it is trying to enumerate the directory named "modules", which does not exist after the default installation. This may be some internal exception or something else but the issue can be easily resolved by creating the directory named "modules" in the root folder.
