QmlProfiler: Timeline: Cannot profile Qml projects

Steps to reproduce:

• open or create Qt Quick Prototype thingy (New File or Project -> Other Project -> Qt Quick UI Prototype)
• profile application and use the 'Stop' button of the Debugger/QmlProfiler toolbar

Current result:

• QmlProfiler starts, but if you close the application or hit stop on the Debugger/QmlProfiler toolbar it stops to profile - but it seems you'll never get the results presented

Note: if not using the 'Stop' button of the Debugger/QmlProfiler toolbar but close the application with its own handles Timeline, Flame Graph and Statistics display information

Additional note: If you used the 'Stop' button at least once the Timeline doesn't display anything.. not even the categories - seems not resettable - restart of QC is necessary.
