This is a different issue, already reported in bug #168516. It happens when signal drag-data-get is emitted in the WebView and DragAndDropHandler::fillDragData is called. It seems that m_draggingSelectionData might be nullptr at that point, we have an ASSERT checking it, though, so it's not supposed to be nullptr.

But this bug happens on drag data received, and DragAndDropHandler::dragEntered is called.

Note there are two different methods named fillSelectionData in PasteboardHelper, this bug happens in one of them and bug #168516 in the other. I can't reproduce any of them, though.
