QT Quick MessageDialog crash

Hi !

I found a problem when using the "MessageDialog" object during testing.

At the very beginning, I noticed that after a number of clicks on buttons, I was losing data (mostly from lists of pointers who I get some data). After hours and hours of tests, I see the MessageDialog is the cause of data lost and crash.

I created an another project and I can confirm it.

When I click  ~80 times a button to get a value from list of pointers (or to get list size), some or all data disappear and make a segment fault during execution. I put an example project, I have set an example project to reproduce the problem.

I don't know why the data is lost and only when a MessageDialog is in qml file.

Steps to reproduce :

• Launch the application
• Click ~80 times the button (less or than, It depends)
• Data loss (I can see this in debug)
• Segmentation fault

I put in a project where the problem appears.

I hope the problem will be found soon, it's very disturbing !

Thank you,

Sincerely
