Thank you for providing a fairly good bug report. Unfortunately, I am not
setup at this time to build and debug in Kdenlive. I have not built
Kdenlive for a few years since the days of KDE4. So, not exactly convenient
for me to use Kdenlive. Also, I am in the middle of something big I have
been putting off for a couple of years to instead tend to a bunch of little
things. I made a mental commitment to devote more attention to that. It
would be nice if a Kdenlive developer took a look at this.
