    Description

      qClipboardPasteTo:
      Line 87: QMimeData *mMimeData = new QMimeData;
      Line 137 and line 143: qWasmClipboardPaste(mMimeData);
       
      If anyone calls QPlatformClipboard::setMimeData between these calls (when file hasn't streamed yet in the file handling loop), the mMimeData will have been deleted before the second access.
