SUMMARY

Adding a new swatch with the + arrow icon in the "Palette" docker in a custom palette crashes the application after a short (2-3 seconds) period where the mouse plays the "loading wheel" animation. This occurs consistently in different files and persisted even after a computer restart. May or may not occur in built-in palettes as well, I don't know.

I hope this isn't a duplicate report, I saw another report where their issue was a freeze, not a crash, and I'm not sure if it's the same or merely similar.

STEPS TO REPRODUCE

1. Edit an image with Krita.
2. Add the "Palette" docker to the main docker panel on the right.
3. Delete all preexisting swatch palettes.
4. Create a new palette with a name.
5. In this new palette, click on the arrow ("Add a new color swatch").
6. Input a name and color. The swatch's group, ID, and whether or not it was marked as "spot color" had no effect on changing the outcome in my experience.
7. Click "OK"
8. Behold as the program stalls and closes itself almost instantly!

OBSERVED RESULT

Program crashes

EXPECTED RESULT

Program doesn't crash

ADDITIONAL INFORMATION

Sorry for lack of technical information like program versions and backtrace files; it's very complicated to me and I couldn't understand the guide page :(
