WebKitBrowser.dll has a manifest with a comClass tag in it, so.. could be a registration-free COM thing?
Yes, looks like that. For some reason WebKitBrowser.dll uses both ways to specify manifest - external file and identical resource entry. It's not a problem, one of them should be picked up anyway. I have some troubles with dev machine, could you attach +ole,+actctx,+tid running latest git (note that registration-free object creation is supported starting 1.7.5)?
