Hi, when I receive currentIndexChanged signal from QComboBox, I call the second function. It's crashing my app. My app is very short, only about 10 files by now, because I started it yesterday.

Anyway, this is halting development. I kind of need that associated data, but I'll try a dictionary too.

Solution is to use a dictionary called _indexMap
