IIRC, at some point after v0.96, Django made
HTML-character-entity-escaping of values in templates the default
behavior; your code assumes the opposite, hence your excessive
escaping problem. I'm sure there's a way to indicate that certain
values should be treated literally and not get HTML-escaped.

Check the transition docs / release notes, and/or try asking on the
django-specific mailing list
(http://groups.google.com/group/django-users )
(You should probably ask there first with any future Django questions too.)

Cheers,
Chris
