My issue seems very similar to http://drupal.org/node/401954, and if it's a duplicate, I apologize.
I recently upgraded to the newest version and ran update.php, cleared caches.
I wanted to have the years in reverse chronological order, 2011, 2010, 2009, etc., up to 10 years prior.
I was to test the validation of the dates, and was given the message in the provided screenshot. One has the configuration for the range, starting 10 years in the past and going to 10 years in the future.
While attempting to submit a previous date, such as seen in the second screenshot, it would give the validation error.
I'm not using date popup, as you can see.
I was pretty sure this wasn't the case with 2.x, as I set up the form with the intention of this date range displaying the current year and all years previously, and hadn't had any users complain of not being able to validate the date.
Do I need to just use the textfield instead, and have users enter the year?
