> Darin, would you prefer this just fixed in WebCore to ensure we don't send null images?  I'd be happy to write that patch, but it wouldn't get fixed today.

I think the right question is what behavior we want when such a cursor is specified. Once we know what behavior we want, then we can figure out how to get that behavior. We could start by figuring out what behavior we have here in WebKit1. I’m thinking that a custom cursor with an empty image should probably result in an invisible cursor. Is that right?

As far as implementation is concerned, it’s OK with me to fix the encoding machinery so it can successfully send an empty custom cursor across the process boundary. I object to the incorrect patch, not the very notion of what the patch is doing. The patch is wrong because if we encode one of these, the decoder will then try to decode fields that aren’t present and consume additional bytes and thus be unable to decode the rest of the stream. That’s a relatively simple mechanical thing to fix.
