The exception itself is not very helpful indeed, but it should contain a 
nested exception with further details.
A good thing with the unique exception codes is that you can find the 
affected code in Flow really easily. In this case it's in 
Doctrine\PersistenceManager::update():

try {
	$this->entityManager->persist($object);
} catch (\Exception $exception) {
	throw new \TYPO3\Flow\Persistence\Exception('Could not merge object of 
type "' . get_class($object) . '"', 1297778180, $exception);
}

Just check your exception logs (in Data/Logs/Exceptions by default) or 
debug that part.
