Debugger: Adding breakpoints to property assignments might end up in broken debug session

Steps to reproduce:

• create Qt Quick Application from scratch
• set a breakpoint onto a property assignment (if it matters: I had used

anchors.fill: parent 

and

anchors.centerIn:parent 

• start debugging

Current result:

• debugger stops at one of the locations (Application Output pane shows some error regarding QQmlExpression depends on non-notifyable properties)
• hit continue
• debugger stops at the other location
• hit continue
• debugger is back at the first location
• this seems to be possible endless
