Created attachment 137540 [details] 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 SOFTWARE/OS VERSIONS Krita: 5766bca3cc (built) Qt Version (compiled): 5.12.9 Version (loaded): 5.12.9 OS Information Build ABI: x86_64-little_endian-lp64 Build CPU: x86_64 CPU: x86_64 Kernel Type: linux Kernel Version: 5.4.0-67-generic Pretty Productname: Linux Mint 20.1 Product Type: linuxmint Product Version: 20.1 Desktop: X-Cinnamon ADDITIONAL INFORMATION Crash log after doing ctrl+C in gdb with the "optional" step: Thread 1 "krita" received signal SIGINT, Interrupt. syscall () at ../sysdeps/unix/sysv/linux/x86_64/syscall.S:38 38 ../sysdeps/unix/sysv/linux/x86_64/syscall.S: Nie ma takiego pliku ani katalogu.

With the Apr 12 5.0.0-prealpha (git 9b24e9c) appimage on Debian 10, I see Safe Asserts even if I deselect the first vector library item before dragging the second shape out. I get Safe Asserts in the 4.4.3 appimage as well This: 13 Apr 2021 14:37:02 +0100: SAFE ASSERT (krita): "srcShape->parent() == excludeRoot" in file /home/appimage/workspace/Krita_Nightly_Appimage_Build/krita/libs/flake/KoShapeManager.cpp, line 501 13 Apr 2021 14:37:02 +0100: SAFE ASSERT (krita): "clonedShapes.size() == originalShapes.size()" in file /home/appimage/workspace/Krita_Nightly_Appimage_Build/krita/libs/flake/KoShapeManager.cpp, line 523 Repated for an additional five times. The number of repeats is varible for each new file, even dragging out the same vector library items in the same order. Leaving the first item selected does not affect the Safe Asserts and does not cause a crash or perceptible freeze.

Line was introduced in 09519feaf10804d7242a44e36b472aa13e809055 and seems harmless, it could even be a if case. I never get a crash nor a freeze, Safe asserts are triggered even if onyl one shape is in the vector layer prior to be D&D, they keep printing over and over againas long as I don't drop the vector shape (that is why they vary) and move the cursor with the D&D action still active. The second line comes from 2617900662ff7046d79249077053ed which could potentially be the backtrace you are seeing. however I never get a crash/freeze so the issue could be or could not be related to those commits.
I don't get a crash, but do get an assert. An additional effect of the bug seems that the previous shapes which are not selected disappear if the shape is dragged over them. Assigning this to myself. @vanyossi if you're working on this already, let me know.
Git commit e164c69a51e18dc89d2645d81154464fe07c0883 by Sharaf Zaman. Committed on 22/04/2021 at 21:28. Pushed by szaman into branch 'master'. Bugfix: assert when a shape from vector library... ... is dragged onto vector layer. Shapes while being dragged, may not have a parent (vector layer) associated with them. This results in srcShape->parent() being null. M +4 -1 libs/flake/KoShapeManager.cpp https://invent.kde.org/graphics/krita/commit/e164c69a51e18dc89d2645d81154464fe07c0883
