multipart formdata bug in Internet Explorer

I have seen it happen in IE 5 and IE 6 (although in IE 6 it requires
stricter conditions)

The bug is that under certain circumstances IE restarts building the
formdata with a (sometimes) different boundary. It results in some fields
submitted twice, or sometimes in some fields missing (depending on which of
the boundaries is used in parsing the request)

I have seen some references to it on internet, but no on really knows.
Currently I am able to reproduce the bug with IE5. With IE6 I can do it as
well, but only when an ActiveX control is present in the form that takes
formatted data.
