This bug appeared after solving other: http://bugs.typo3.org/view.php?id=1537

The solution is modify after the line 489 of tslib/class.tslib_pagegen.php the next code:

$finfo = @finfo_open(FILEINFO_MIME);
$iconMimeType = ' type="'.finfo_file($finfo,$favIcon).'"';
finfo_close($finfo);

...and put this:

$finfo = @finfo_open(FILEINFO_MIME);
if ($finfo) {
$iconMimeType = ' type="'.finfo_file($finfo,$favIcon).'"';
finfo_close($finfo);
}
