The Array $wgFileBlacklist in DefaultSettings.php should contains the extension "php5". Some Hosters e.g. 1und1.com use this extension for scripts using PHP5.
The following line in LocalSettings.php can fix it as workaround: $wgFileBlacklist[count($wgFileBlacklist)] = "php5";
Or just $wgFileBlacklist[] = "php5"; The patch for this is so trivial I'm going to mark this as patch reviewed, because it may as well be.
Added in r16899.
