SoftAssert in qmlprofilerstatisticsview.cpp:303 seems to be a legit case as it can be easily triggered. Please check whether this should be silenced or has another cause that should be fixed..
Steps to reproduce:
- create Qt Quick Application - Empty from template (I've used Qt5.9 kit if that matters)
- start profiling
- after some seconds stop the profiler
- click on one of the events inside the timeline (triggers the soft assert)
