AttributeError: 'NoneType' object has no attribute 'log'

jjpj reported this one on IRC.

This traceback is seen, but is masking the fact that it can't log another traceback (namely, clearsilver is not installed).

Traceback (most recent call last):

  File "/usr/lib/python2.3/site-packages/mod_python/apache.py", line 299, in HandlerDispatch
    result = object(req)

  File "/usr/lib/python2.3/site-packages/trac/web/modpython_frontend.py", line 87, in handler
    gateway.run(dispatch_request)

  File "/usr/lib/python2.3/site-packages/trac/web/wsgi.py", line 87, in run
    response = application(self.environ, self._start_response)

  File "/usr/lib/python2.3/site-packages/trac/web/main.py", line 430, in dispatch_request
    env.log.exception(e)

AttributeError: 'NoneType' object has no attribute 'log'

Here's the true traceback:

Traceback (most recent call last):

  File "/usr/lib/python2.3/site-packages/trac/web/main.py", line 401, in dispatch_request
    req.hdf = HDFWrapper([default_dir('templates')])

  File "/usr/lib/python2.3/site-packages/trac/web/clearsilver.py", line 135, in __init__
    raise TracError, "ClearSilver not installed (%s)" % e

TracError: ClearSilver not installed (No module named neo_cgi)

I'm going to wrap the env.log in an if like the other except blocks near it in a sec.
