           Summary: QtWebKit converts int32 parameters passed to NPAPI
                    plugin to Double. Therefore
                    WMP::player.controls.setVolume does not work
           Product: WebKit
           Version: 420+
          Platform: PC
               URL: http://jsbin.com/unulu3
        OS/Version: Windows 7
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Plug-ins
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ggonen at nds.com


The bug is demonstrated in the attached javascript page (http://jsbin.com/unulu3).
Open a page containing the ms windows media player mpapi plugin, and try to set the volume level programmatically
using: player.settings.volume = newValue;
It fails without an error mesage.
If you open the same page with IE, FF, or Chrome it works.

Analysis:  
QtWebKit converts int32 parameters passed to NPAPI plugin to Double.

I attach my fix (in the file c_utility.cpp).
