Qt Creator won't tell me what part of my code is causing my program to crash

My Qt program is crashing, so I tried to debug it with Qt Creator. The problem is that when it crashes in the debugger, Qt Creator only shows me internal Qt files, and doesn't show me what part of my code is causing my program to crash. When I click <more> to try to figure out what part of my code is causing my program to crash, Qt Creator itself crashes. See the attached video (the video ends when Qt Creator crashes).
