req.args.get('email') returns a list

[asterix@…]

I don't know where the bug is, but captcha plugin fails when an anonymous user try to create (or just preview) a ticket.

here is the traceback:

Traceback (most recent call last):
  File "/usr/lib/python2.5/site-packages/trac/web/main.py", line 444, in _dispatch_request
    dispatcher.dispatch(req)

    email = req.args.get('email', '').strip()
AttributeError: 'list' object has no attribute 'strip'

After some debugging, req.args.get('email', ) returns a list like that [u, u'test@…'] if I put test@… in email field.

is there some other email field on the page that could cause this to be multi-valued?

no there is not. email field contains only one email, no space arround. I tested to add emails to CC fielld, but that changes nothing: They don't appear in the email field.
