TypeError: decoding Unicode is not supported

How to Reproduce

While doing a GET operation on /projects/analistas/browser/Baselines, Trac issued an internal error.

I'm trying to migrate some TRAC projects from a old 0.12dev-r7634 to a new 0.12.5 installation

Request parameters:

i have made the following changes on "/usr/lib/python2.7/dist-packages/trac/web/api.py" and now works:

    @property
    def path_info(self):
        """Path inside the application"""
        path_info = self.environ.get('PATH_INFO', '')
        try:
            return unicode(path_info, 'utf-8')
#        except UnicodeDecodeError:
#            raise HTTPNotFound(_("Invalid URL encoding (was %(path_info)r)",
#                                 path_info=path_info))
        except (TypeError, UnicodeDecodeError):
                return path_info

    @property

No, that is a TracForgePlugin issue, not a Trac issue.

The issue is probably caused by changing environ['PATH_INFO'] to unicode instance.
