length_is filter causes an exception if it's used with None intead of something that has len() method. According to docs this should never happen (tags and filters fails silently).

Exception Value:  	

Caught an exception while rendering: object of type 'NoneType' has no len()

Original Traceback (most recent call last):
  File "/usr/local/lib/python2.5/site-packages/django/template/", line 71, in render_node
    result = node.render(context)
  File "/usr/local/lib/python2.5/site-packages/django/template/", line 250, in render
    value = bool_expr.resolve(context, True)
  File "/usr/local/lib/python2.5/site-packages/django/template/", line 559, in resolve
    new_obj = func(obj, *arg_vals)
  File "/usr/local/lib/python2.5/site-packages/django/template/", line 523, in length_is
    return len(value) == int(arg)
TypeError: object of type 'NoneType' has no len()
