Summary [Qt] Plugin asking for NPNVnetscapeWindow can crash webkit
Christophe Oosterlynck
Reported 2011-10-13 08:15:52 PDT
When using a QGraphicsWebview in a scene that is not viewed by any graphicsview, webkit will crash when the plugin asks for NPNVnetscapeWindow. If there is no graphicsview (client->ownerWidget() returns 0, see patch), asking for NPNVnetscapeWindow should return 0.
