OS: Ubuntu Core 20 (XFCE/xfce)
Word size of FreeCAD: 64-bit
Version: 2022.1008.14555 (Git shallow)
Build type: Release
Branch: (HEAD detached at 2022.10.08-edge)
Hash: 39bee7c
Python version: 3.8.10
Qt version: 5.15.5
Coin version: 4.0.1
OCC version: 7.6.3
Locale: English/United States (en_US)

This version is crashing if you just delete something from the tree view.

Deleting using the undo function works without crash.
But just click and delete a object in tree view crashes the program.

This behavior happens since a couple of version.
I guess it is something very small but this bug disturbs the workflow a lot.

Can you please launch FreeCAD in a terminal, and then paste the printed call stack information after crash?

What i did was:

  1. start fc
  2. new doc
  3. new part design body
  4. new sketch
  5. close sketch
  6. new body
  7. new sketch
  8. draw something in the sketch
  9. close sketch
  10. delte this (second) body
  11. crash

This happens since several daily build versions. I guess it is something small because deleting the body while using the ctrl-Z still works in the above situation.

(my workaround to get rib of not longer needed stuff in the tree view is to open it in vanila FC and delete the stuff there.)

The above commit shall fix the crash, which happens in DAGView. BTW, are you actively using DAGView? This view is not actively maintained right now, and is quite complex. To avoid unexpected behavior, you might want to disable it if not using. You can do this by using Tool -> Edit parameters. And set parameter BaseApp/Preferences/DockWindows/DAGView/Enable to False.

I used it one time, but did not need it regularly. So i can switch it off with no harm of workflow. Thx for fixing.
