Thank you, Marcus. I didn’t reproduce for tst1.lyx but I did for tst5.lyx. The
backtrace seems to be different from your previous report, so they can be
pointing to different causes.
Since QtCreator crashes with LyX, I couldn't do a precise debug but LyX’s
standard output with option ‘-dbg any’ is as follows:
