gdb backtrace

Krita 4.1.1-4 (Arch Linux)

Tested with fresh configuration (removing existing ~/.local/share/krita,
~/.config/krita*)

Reproducible: Always but inconsistent in how many actions required prior to
crash

Steps:
1. Create new document (ctrl+n)
2. Layer > Flatten Image (ctrl+shift+e)
3. Perform action, such as draw with brush tool on "root Merged" layer
4. Undo/Redo entire stack several times (ctrl+z, ctrl+shift+z)
(undoing brush stroke, flatten, then redoing)

Hold down ctrl+z to undo, then hold down shift in addition to quickly redo.
Repeat.

Results:
SIGSEGV

Expected:
Proper undo/redo of flatten.

Hm, I cannot reproduce this with the latest build from git master. Could you
give the nightly appimage a try? See

Unable to reproduce using 'krita-4.2.0-pre-alpha-127857b-x86_64.appimage'.
Assume resolved.
