Assignee: krita-bugs-n...@kde.org

SUMMARY
In some configurations, Halftone filter crash krita
Note, problem doesn't occurs with Krita 4.4.3, so it looks like a regression
for Krita 5
STEPS TO REPRODUCE

3. Change mode from "Intensity" (or "Independent Channel") to "Alpha"
> Crash

1. Open properties on an existing filter layer "Artistic > Halftone"
2. Change mode from "Intensity" (or "Independent Channel") to "Alpha"
> Crash
--
1. Create a document
2. Ensure mode is in "Intensity"
3. Change generator to "None"
> Crash
(no crash if mode is "Independent Channels")
--
1. Create a document

"Filter>Artistic>Halftone" (not a filter layer)
> Crash
--
1. Create a document in Krita 4.4.3
2. Add a filter layer, "Artistic > Halftone"
3. Change mode from "Intensity" (or "Independent Channel") to "Alpha"
4. Change generator to "None"

OBSERVED RESULT
Krita crash with segmentation fault.
EXPECTED RESULT
Krita doesn't crash :)
Problem seems related to "None" generator (that I suppose to be selected by
default when selecting 'Alpha' mode) but I can't confirm it (just an idea...)
