Created attachment 104279 [details] QML example demonstrating the issue It is possible to provoke the Kirigami PageRow component into attempting to deref a null value by pushing a new page to the pageStack. Steps to Reproduce: 1. Load the attached QML file with qmlscene 2. Click the "Demonstrate the bug" button 3 times or more (it doesn't need 'rapid' clicks, just repeated clicks to trigger the bug). 3. Observe the console output of qmlscene: on or more TypeErrors should be reported, the first of which references line 436 of the PageRow source. Burried inside the PageRow component, at lines 436 the following is attempted: ``` // at line 435: onPageChanged: { page.parent = container; page.anchors.fill = container; } ```
Qt version: 5.7.1
