QT QML/C++ application crash on exit

I have a QML / C++ hybrid application which is fairly complex with a few threads updating data in the background. Everything works flawlessly except when I make a certain ListView visible, populate it and then exit the application, the debugger breaks with an assertion failure at the following location:

QDeclarativeAbstractBinding::~QDeclarativeAbstractBinding()
{
    Q_ASSERT(m_prevBinding == 0); //<---- THIS GUY IS THE OFFENDING LINE
    Q_ASSERT(m_mePtr == 0); 
}   

and here is the stack trace:

Edit:

The question: How can I eliminate this problem ? What might be wrong with my code ? There is no information regarding how this can happen.

Sorry for the late response, I inspected my QML file and discovered that the bug occurs when I define multiple "PropertyChange" elements with the same target in a single "State" element. I grouped all the property changes for the same item in a single "PropertyChange" element and the problem disappeared. But it's quite strange and the assertion failure is not very definitive. Also tried to reproduce the bug with this information but couldn't succeed. Probably there are other factors that I miss. Thanks anyways.

It's difficult to know what's going on without seeing the application code. Also if it is possible to create a standalone example that reproduces this crash, I suggest filing a bug at https://bugreports.qt.io.
