Patch against svn trunk

If you try to set the 'window-features' GObject property to NULL, then webkit-gtk crashes. You may ask, why would I want to set that property to NULL? Well, if I use the Glade application to construct a user interface containing WebKitWebViews, then it happens.

I have attached a patch.
