(Cannot read property 'anchors' of nul).
Product: kirigami
Version: Master

Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general

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;
}
```
