IndexError: list index out of range

hi guys,
thanks for sharing this app, i really like it. just one strange thing, one some pages i'll get a django error message, even if i am still able to open the page:

File "/home/user/webapps/wiki/lib/python2.6/django/core/handlers/base.py", line 178, in get_response
response = middleware_method(request, response)

File "/home/user/lib/python2.6/htmlmin/middleware.py", line 25, in process_response
response.content = html_minify(response.content, ignore_comments=not keep_comments)

File "/home/user/lib/python2.6/htmlmin/minify.py", line 36, in html_minify
if not between_two_tags(minified_line, minified_lines, index):

File "/home/user/lib/python2.6/htmlmin/util.py", line 11, in between_two_tags
if current_line and not current_line.startswith('<') and not all_lines[index-1].endswith('>'):

IndexError: list index out of range

any idea? or is it my html? i double checked everything.
thanks,
horndash

ps. there are two typos in the documentation:

it says: from htmlmin.decorator import no_minified_response
but it should say from htmlmin.decoratorS import noT_minified_response

Start with the traceback locations in htmlmin/middleware.py, htmlmin/minify.py, and htmlmin/util.py, then reproduce the error using the affected page HTML. Confirm the response can be minified without an IndexError, and separately check the documentation examples for the two reported import typos.
