Crash log for 20.08.0 Appimage
SUMMARY
When changing the speed for a clip, Kdenlive applies the effect, i.e. you see
the clip's length change, but as soon as that happens, the application crashes
and the change is lost. Reloading the project gets you back to where you were
prior to changing the clip speed.
STEPS TO REPRODUCE
1. Add a video clip to the timeline.
2. Right-click on the clip and choose "Change Speed".
3. Adjust the speed to a small number.
It seems any number below 30% will cause the crash. This crash is also present
in version 19.12.3, though I only checked the specific values in the 20.08.0
Appimage.
OBSERVED RESULT
App crash.
EXPECTED RESULT
Not an app crash. Only the clip's speed being adjusted to the given value.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Kubuntu 20.14 LTS AMD64
KDE Plasma Version: 5.18.5
KDE Frameworks Version: 15.68.0
Qt Version: 5.12.8
Kernel Version: 5.4.0-45-generic
ADDITIONAL INFORMATION
On step #3 above, I tested the values and observed these results:
110% = No crash
90% = No crash
50% = No crash
25% = Crash**
15% = Crash**
40% = No crash
30% = No crash
29% = Crash**
It seems the crash occurs whenever any speed value smaller than 30% is used.
