You seem to be using an old version of django-tagging (your issue is discussed here!) which itself depends on an old version of Django.

Upgrade django-tagging to the latest version; 0.3.1 seems to be the latest release, but the project hasn’t seen any activity since 2010 — I don’t know if it’s still alive or just very stable.
