A GUI program with Model-View-Delegate pattern. It work fine on Mac OSX 10.10.5, but crashed on 10.10.1 when clicked on view's item. Qt framework version: 5.5.1. It's a bug of framework?

In the program:
view is customized base on QListView
model is customized base on QAbstractListModel
proxy-model is customized base on QSortFilterProxyModel
delegate is customized base on QItemDelegate

Hi,

Do you also have OS X accessibility active on 10.10.5 ?
