Description
In our project we have listview in which we have complex delegate which contains qml AbstractButton element. When we use "indicator" property our application sometimes crashes when model calls endResetModel(). I add simple custom model in our application and reset it very quickly removing all model data, and then resetting and adding new data to model. So application eventually will crash on windows, ubuntu desktop linux and target linux.
I can't reproduce the issue in test application so all i can do is share with you stacktrace from coredumps, hoping it will be enough.
