Accessing request.POST can trigger a ValueError

[wichert]

I just found this in an error log:

File myapp/image.py, line 38  in image_upload
    image = request.POST.get('image')
File uild/bdist.linux-x86_64/egg/webob/request.py, line 806  in POST
    keep_blank_values=True)
File python2.7/cgi.py, line 507  in __init__
    self.read_multi(environ, keep_blank_values, strict_parsing)
File python2.7/cgi.py, line 621  in read_multi
    raise ValueError, 'Invalid boundary in multipart form: %r' % (ib,)
ValueError: Invalid boundary in multipart form: ''

I'm not entirely sure what should happen in this kind of scenario, but a dictionary raising a ValueError on get is very weird.

This belongs in the webob issue tracker, but I'm also not sure what you'd expect to see.. A subclass of ValueError called MalformedRequestBody or something?

I think I would expect to see None here. Having a dictionary-style interface raise an exception for get() feels very wrong.
