ZF 1.12: see full path in exception message

I’m getting this error:

Access Denied
Ooops! The Application is not accessible at the moment. Please try again later or contact the administrator
Exception information:

Message: The given destination is not a directory or does not exist
Stack trace:

#0 /var/www/mycompany.eu/library/Zend/Form/Element/File.php(512): Zend_File_Transfer_Adapter_Abstract->setDestination('/var/www/mycomp...', 'file')

As you can see the path (first parameter in setDestination() ) is truncated ( mycomp... ). How can I see the full path?
