trac tags stopped working with 0.11 trunk

[alex@…]

sometime after r6100 of trac trunk (0.11) my tractags plugin stopped working, when I click on the tags tab at the top of the page (trac nav bar)

I get the following error:

Oops…
Trac detected an internal error:
HTMLParseError: malformed start tag, at line 120, column 2

The exact same error happens on another trac project runnig on a completely different system (OSX) So it appeared at the same revision of trac trunk, therefore it ought to be one of the changes made since...r6050 ?

Most likely this is due to the context refactoring that went on the trunk on 11/9/07, see here: ​http://trac.edgewall.org/changeset/6139. Christian sent an email to the trac list about it on the same day. Here's a quote from that email:

The context-refactoring branch is going on trunk today. If you're an early Trac 0.11dev adopter, the implications of this depend on whether you're using plugins or not. If not, the core Trac is still pretty solid and the update should not be problematic. But if you are using plugins, chances are that they're going to break in some ways or another.

It should be relatively easy to adapt the 0.11dev plugins to the new API. For a general overview of the API changes that were discussed the last few months, see the following mail on trac-dev:

Fixed in 0.6.

[Christophe de Vienne]

(In [3314]) Disable a debugging purpose feature which make win32 deployment fail. This fix #2160.

Replying to cdevienne:

This is a mistake, I wrote 2160 instead of #2168 in my comment. Sorry for the noise.
