(I initially tried to report this bug through DRKonqi, but DRKonqi was unable to submit the report.)

Application: kdenlive (21.12.2)
 (Compiled from sources)
Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.15.11-gentoo-x86_64 x86_64
Windowing System: X11
Distribution: Gentoo/Linux
DrKonqi: 5.24.0 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:

I inserted a clip in the timeline. I right-clicked on it, then enabled time remapping.

The clip I wanted to time remap had some action in the middle that I wanted to slow down to 50%. In other words, I wanted to play the clip at 100% at the beginning, 50% in the middle and 100% at the end. So in the time remapping dialog, I added two keyframes. I selected one of the two keyframes and wanted to change the speed percentage from 100 to 50. So I typed 50 in the appropriate text box, pressed Enter and Kdenlive crashes.

I have repeated the same steps three times, causing Kdenlive to crash consistently every time.

The problem clip came from a Sony FDR-AX53, was encoded with their XAVC-S codec (basically H.264 with a higher profile and bitrate than AVCHD) and was shot at 100 fps. The project uses 50 fps.

The crash can be reproduced every time.

-- Backtrace:
