Bug ID: 435670
Summary: Adding two shapes from vector library results in an
assert
Product: krita
Version: nightly build (please specify the git hash!)
Platform: Mint (Ubuntu based)
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Layers/Vector
Assignee: krita-bugs-n...@kde.org

Crash log for all threads
SUMMARY
If you add a shape from vector library, and then, without deselecting that
shape, you add another one, you'll get a safe assert window, and then a
crash/freeze/another assert.
STEPS TO REPRODUCE
1. Build Krita with safe assert dialogs on.
2. Drag a shape from a vector library to the canvas (remember that Pepper &
carrot shapes are white and will be invisible on white canvas). Do not unselect
the shape.
3. Optional: switch to another vector library.
4. Drag another shape on the canvas.
OBSERVED RESULT
In case of "optional", I get a weird situation when I don't have my X11 hang
up, but the safe assert window doesn't react to either Abort or Ignore.
If I break it in gdb, I get the crash log as shown below.
In case without the optional step, my whole X11 hangs up so I cannot tell what
the backtrace is.
EXPECTED RESULT
No safe asserts. No crashes. No freezes.
NOTE
On Krita 4.4.3 you already get those safe asserts:
SAFE ASSERT (krita): "srcShape->parent() == excludeRoot" in file
/home/appimage/workspace/Krita_Release_Appimage_Build/krita/libs/flake/KoShapeManager.cpp,
line 512
SAFE ASSERT (krita): "clonedShapes.size() == originalShapes.size()" in file
/home/appimage/workspace/Krita_Release_Appimage_Build/krita/libs/flake/KoShapeManager.cpp,
line 534
