Enabling the highlight extension with Python 2.4 causes a traceback in pygments. See: https://bitbucket.org/birkenfeld/pygments-main/issue/749/not-compatible-with-python-24
This is surely due to a change in a recent Pygments and nothing to do with Mercurial or the highlight extension. Can't see us doing anything about this on our end.
Sure. It was meant more as a notification, so we are aware where this comes from in case someone else runs into the problem.
