           Summary: DragData::asFilenames push same file to result in
                    windows platform
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Windows 7
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: huangxueqing at baidu.com


It seems like a careless error in DragDataWin.cpp, DragData::asFilenames call windows api
        for (unsigned i = 0; i < numFiles; i++) {
            if (!DragQueryFileW(hdrop, 0, filename, WTF_ARRAY_LENGTH(filename)))
                continue;
            result.append((UChar*)filename);
        }
which always push 0-index file to result. If you drag some files to WinLauncher, thie filelist return same file name.
IMO, use DragQueryFileW(hdrop, i, filename, WTF_ARRAY_LENGTH(filename).
