[twill] Working around <br/> issue?

Thank you. Very helpful!!! I have used the following code:

go http://www.google.com/voice#trash
fv 1 Email email
fv 1 Passwd passwd
run "b=get_browser();b.result.page=b.result.page.replace('<br/>','<br />');"

It works as I can confirm with a save_html. However, when doing a showforms I still get:
>> showforms
Traceback (most recent call last):
  File "/usr/bin/twill-sh", line 20, in <module>
  File "/var/lib/python-support/python2.5/twill/shell.py", line 387, in main
  File "/usr/lib/python2.5/cmd.py", line 142, in cmdloop
    stop = self.onecmd(line)
  File "/usr/lib/python2.5/cmd.py", line 219, in onecmd
    return func(arg)
  File "/var/lib/python-support/python2.5/twill/shell.py", line 42, in do_cmd
    print '\nERROR: %s\n' % (str(e),)
  File "/usr/lib/python2.5/HTMLParser.py", line 59, in __str__
    result = self.msg
AttributeError: 'ParseError' object has no attribute 'msg'

Any idea how I can figure out what's causing this? I'd like to avoid sending the HTML to a public
list, but will gladly send over personal (individual) email.

Thank you
