title: PHPExcel_IOFactory::load throwing uncaught Exception and caused script halt
body: <p>i've verified that the file is exists, this is my script to load the document</p>
  
  <pre><code> try{
         $this-&gt;obj_global = PHPExcel_IOFactory::load($this-&gt;file_name);
         $err_msgs = '';
  
      }catch(ErrorException $e)
      {
          $err_msgs = $e.getMessage();
  
      }catch (Exception $e)
      {
          $err_msgs = $e.getMessage();
  
      }
  </code></pre>
  
  <p>i read my log and found, error messages from Excel5.php line 995 with messages contain "Call to a member function getBlipType() on a non-object" as i believed that, the parser try to loads the graphics object and failed. 
  btw i've try to read phpexcel discussion forum, and found nothing about the issue. i don't know if this is a bug or the problem comes from my corrupted excel file. but fortunately i can load and read that file correctly without any error when i try to change my loader script and set my reader setReadDataOnly(true); but another problem is, when working with this method, i cannot read my date column correctly. </p>
  
  <p>my question are, how can i caught this type of error, i've try to catch it but it's not working, script just halt?  </p>
  
  <p>please any help, i've read this too.
