Subject: Problems with error handling

I am working on a codeigniter 2 project with php-activerecord models. I am having troubles with some models and I can't seem to find a way to catch errors before they crash my application. Here is a test example:

My Model looks like this:

class Cohort extends ActiveRecord\Model
{
        static $has_many = array(
        array('course_outcomes')
    );    
    }

My controller function does this:

try
{
            $this->view_data['test'] = Cohort::find(1);
        }
         catch (\ActiveRecord\RecordNotFound $e)
 {
               echo $e->getMessage();
         }

I have also tried this:

try
    {
             if($cohort = Cohort::find(1))
        {
                $this->view_data['test'] = $cohort;
            }
            else
        {
                throw new \ActiveRecord\ActiveRecordException('It hasn't worked.');
              }
        }catch(\ActiveRecord\ActiveRecordException $e)
    {
            echo $e->getMessage();
        }

This works if Cohort::find(1) returns a result, which is the case if I comment out the association. However, something in my association breaks the query, but that's not my question. My question is why does the try...catch block not catch an exception? Whatever I do, an invalid query seems to immediately break my application and return a blank screen. Can anybody help?

PHP is version 5.3.6 and error reporting is turned on (and works for most other php errors).

What happens if you just catch all exceptions in your controller? (I'm not suggesting this as a solution, but it'd be useful to figure out if any exceptions at all are being thrown):

try
{
  $this->view_data['test'] = Cohort::find(1);
}
catch (Exception $e)
{
  echo $e->getMessage();
}
