[Bug 1514173] [NEW] [listitemlayout] setting RichText format with html image tag leads to crash (segfault)

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

ListItemLayout defines a default main slot, which is currently the
internal class UCThreeLabelsSlot.

ListItemLayout currently doesn't set the QML context of the
UCThsreeLabelsSlot, and UCThreeLabelsSlot doesn't set the QML context of
its internal UCLabels.

This leads to a segfault when Qt tries to access the QML context of any
of the predefined labels in ListItemLayout.

The following test case triggers the crash:
ListItemLayout {
    id: layoutTestQmlContext
    title.text: "<html><body><p dir='ltr'>TEST <img align=absmiddle height=\"10\" width=\"10\" src=\"file:///test.png\" /> </p></body></html>"
    title.textFormat: Text.RichText
}
