Filter layer crash reproduction case

I copied an HSV adjustment layer from one file to another.  This produced some sort of invalid layer that crashes every time the opacity is adjusted.  It has something to do with the animation key frames on the layer - if you delete the keyframes first, there is no crash.

1.  Open the attached file
2.  Adjust the opacity of the filter layer
3.  Crash


No crash ;)

Windows 7, Krita 5.0.6

I can Confirm this crash with the 5.0.6 appimage and the Jun 02 5.1.0-prealpha (git 49171d80dc) appimages.

It seems to be caused by 'internal logic' not taking account of the situation.
The Filter Layer has opacity keyframes on it and the first one is not at frame-0.

If you select a frame and change the opacity of the layer in the Layers docker then the opacity keyframe value is changed for that layer, if it has an opacity keyframe on it.
If it does not have an opacity keyframe on it then the previous opacity keyframe value is changed.

For this layer, and similarly constructed layers, if you select a frame that is before the first defined opacity keyframe then there is no previous opacity keyframe and it crashes.

The same thing happens for a paint layer with opacity keyframes on it (and probably other types of layers that can have opacity keyframes on them).
