Bug ID: 414668
Summary: Crash with onion skins when using opacity keyframe on
a layer with non-animated content
Product: krita
Version: nightly build (please specify the git hash!)
Platform: MS Windows
OS: MS Windows
Status: REPORTED
Severity: crash
Priority: NOR
Component: Animation

Example .kra file to induce the crash
SUMMARY
This happens with the latest 4.3.0 prealpha Windows build g5924da4972 and also
the 4.2.8 Linux appimage.
STEPS TO REPRODUCE
1. Put opacity keyframes on a layer which is not itself animated. This may be
done to give some kind of fade in/out effect for the layer content.
2. Click on the onion skin icon for that layer in the Timeline docker.
A .kra file is attached that illustrates this.
OBSERVED RESULT
Crash
I attach the Windows crash log.
EXPECTED RESULT
Not crash
I know that there's no point in trying to show onion skins for this situation
but if it can be done them somebody will try to do it (like I did).
A workaround is to make one animated frame by using Create Duplicate Frame on
frame-0 of the Timeline so it fills up with held frames of the layer content.
However, this can't be done if an opacity keyframe has been placed on frame-0.
