Recent versions of mozilla appear to change how multipart/form-data is hand=
led
by the client when an input type=3Dfile is used.

mozilla-0.9.2.1 and the two versions of netscape that I've tried apparently
send all form data such that empty file fields are still seen as file objec=
ts
to Zope.

mozilla-0.9.9 sends data such that empty file fields are empty strings (such
as a regular input type=3Dtext).

This of course breaks Zope products that check file field uploads by using =
the
_.len(request['file']).read() method. They'll need to be wrapped in an if
statement now, I guess.

Has anyone else seen this?

I've talked to some mozilla people and their take is that mozilla was and
still is doing the right thing.
