No - I don't think it should.
Make sure you have Debugging enabled in your config.php (see config-dist.php for the lines). Try again.
It's also worth trying the web upgrade (again with Debugging on) to see if it makes a difference.
If there's anything you are not telling us and you have had a *failed* upgrade, make sure you restore both the database and moodledata before trying again
