Debugging problem in QT/QML application

KK2014 — Wed, 25 Mar 2015 13:20:40 GMT

I have Identify application and when I want to test debuging mode in onMousePressed signal in application when I click feature debug mode open and goes to the break points after two seconds or when I click the Step Over button gives exception and open Assembly output.How can I solve this problem?
