Error "global name 'True' is not defined"

[matt.faure@…]

After publishing a page (without preview), I got the following error:

Trac detected an internal error:
global name 'True' is not defined

With the associated Python traceback:

Traceback (most recent call last):

NameError: global name 'True' is not defined

Thus, my page is unusable :-/

I checked ticket #1011 but I didn't use RST (I also applied the diff, but it was unsuccessfull).

I don't remember exactly what I typed, but perhaps it could be a problem with nested lists and/or titles.

Contextual informations: debian stable, python 2.1.3
