> From code inspection, I see that WebKit1 is definitely calling getNPObject(), it's in WebNetscapePluginView.mm. This code path is for in-process plug-ins, so it should be hit when Safari runs in 32-bit WebKit1 mode.

That would certainly explain it.

It'll only manifest for plugins that fetch the script object for their element, and the memory will be freed when the page is torn down, so it's a leak you'd only notice if you were adding & removing plugins on a page for quite a while.
