TYPO3 Core

BE typo3_src-4.5.2/t3lib/thumbs.php only shows filename instead of image
because somehow sometihing/a byte is in the output-buffer whitch makes the image-data invalid.

calling ob_clean() in line 252 like

if($fd = @fopen($this->output,'rb'))    {
                                        ob_clean();
                                        header('Content-type: image/'.$outext);
                                        fpassthru($fd);
                                        fclose($fd);
                                } else {
                                        $this->errorGif('Read problem!','',$this->output);
                                }

solves the problem, is a working workaround.
