Add tags during addition of new contact fail to add tags

I have an install of CiviCRM 3.3.1 with the following configuration:

• Apache/2.2.17 (FreeBSD) mod_ssl/2.2.17 OpenSSL/1.0.0c DAV/2 mod_fastcgi/2.4.6
• MySQL/5.1.39
• PHP/5.2.16

I'm seeing an issue where when I try to create a new contact (/civicrm/contact/add&reset=1&ct=Individual) with tags by opening the fieldset towards the bottom of the form and typing in tags into the autocomplete tag interface, they are not being created when the new contact is successfully saved. I have two fields there that are both autocomplete fields and as a test, I am attempting to add one tag that is in the system already, and one that is not for both fields. No tags at all are saved when the new contact is created.

I searched as best I could on the issue queue, but could not find any issues that seemed to depict this problem.

Please let me know if there is further testing that would help in diagnosing this issue.
