The snapshot of 23-11 still crashes on the following actions:
1) Move cursor over any Qt class name and press F1. Documentation
window opens on right side of screen.
2) Now move the cursor to an empty line and press F1 again. After a
couple of seconds, QtCreator crashes.
This is on OS X. I also tried on Linux. There QtCreator doesn't crash,
but freezes for about 20 seconds or so.
