QSortFilterProxyModel crashes on filtering item out

  • I have included a zip file that contains my test case for this behavior and I do not know the internals of QT well enough to know what is going on. The program crashes because QVector gets out of range.

    How to cause crash in test case:

    1. type "Tom" in search bar
    2. edit "Tom" and change it to something like "Harold"
    3. click out of box to commit change and the application will crash with and index out of range error

    I am not sure how to make editing cells and the active sorting/filtering work at the same time. I assumed it was trivial and this behavior is necessary for my application.
    Any help is appreciated! Link to the test case: https://1drv.ms/u/s!AorbqJ_2ZaIz3mTpOfaPlUXJEoRC

    It also crashes on OS X.
