Magento: Fatal error: Call to undefined method Mage_Adminhtml_Block_Abstract::getexceptions()

When I tried to export or import any profile, then I got a fatal error:

Fatal error: Call to undefined method Mage_Adminhtml_Block_Abstract::getexceptions() in ……./app/code/core/Mage/Adminhtml/Block/System/Convert/Profile/Run.php on line 167

To remove this problem follow below process:

1. Go to file which showing in fatal error.
2. Comment line 167 and 168, then it will show like:

       // if (!is_null(parent::getExceptions()))
       //     return parent::getExceptions();

3. Go to line number 197 and comment it so it will show like:

       // parent::setExceptions($exceptions);

It will run you import/export code….
