"Attach file" fails with HTMLParserError

[anonymous]

For any ticket in trac, if I click on "Attach file", I get the error below. I'm running trac 10.4 on freebsd 6.2. The trac environment was upgraded from 10.2. I'm using the default templates that come with 10.4 w/o modification. trac.log shows the exact same backtrace as below and nothing else. I'm also running trac accountmanager and trac webadmin.

It seems like an HTML error somewhere but can't figure out where from the backtrace. Any help?

Oops...

sorry, I'm an idiot. I was using an older set of templates with bugs in it.
