           Summary: When a live frame is moved across pages, some plug-in
                    DOM methods cease to function
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Frames
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ap at webkit.org

There is a per-Page PluginData object which Plugin and MimeType reference. If a document moves to another pages, these references should all be updated.

On my test cases, this results in calls like navigator.plugins[0].item(0).enabledPlugin return null, but if we missed a null check somewhere, it can also crash once the other page is destroyed.
