I have experienced this problem a number of times. Each time has been while
working on a complex project, and each time I have not been able to
reproduce it. The steps leading up to the problem are not consistent
either, though the work I am doing at the time often involves the Speed
effect. The only way I have found to reliably recover is to quit kdenlive
and reload the project. When I do this the affected clip has disappeared. I
have a loose theory that the clip no longer really exists, but its
representation in the timeline remains due to a bug.

I have never reported this as a bug as I have been unable to reproduce it,
or describe a real pattern to the steps leading up to the bug occurring.

Like you I was running Fedora 29, with the version of kdenlive packaged by
Fedora. I have recently upgraded for Fedora 30, so am no longer certain
which version of kdenlive I was using when the bug occured. I am planning
to upgrade to the refactored branch releases once I have completed two
projects, currently in flight.
