Loading event data locks up

1. Create a new Qt Quick Application project using component set Qt Quick 1.1.
2. Configure the project to use a kit with Qt 4.8.5.
3. Run this project in the QML Profiler.
4. After some seconds, stop the execution.
5. See the "Events" tab of the QML Profiler.
   You'll see a progress bar: "Loading data, 25%". Nothing more will happen.

Loading data should not lock up. If QML profiling isn't possible with Qt 4.8 anymore, Creator should not offer it in the first place.
