Profiler runs on after pressing "Stop" to early. (And there is no way to stop it then except by starting a new profiling)

1. Create a simple Qt Quick application or QML project. (Examples should fit)
2. Go to the Analyze view
3. Press the "Start" (Profiling) button and immediately afterwards the "Stop" (Profiling) button
(Stop must be pressed before the time starts to run or the widget becomes visible)
