Created attachment 308742 [details] Demo page Create a test page that checks for pasted files with an onpaste handler and check if there are pasted files. In Safari and webkit nightly, trying to use a FileReader with that file throws a "Failed to load resource: The operation couldn’t be completed. (WebKitBlobResource error 4.)" error in the console.
