Problem description

When I was developing a patch allowing for manipulation of objects with spacemouse/spacenavd devices ( #18098 ) I have stumbled upon a segfault.
It was easiest to trigger with 6-dof controller (with above PR applied, possibly by high event rate of placement adjustments) but it is also possible to trigger it sometimes with a mouse wheel only.
I have tested below procedure with FreeCAD 0.20.2, 0.21.2 and 1.1.0.
Segfaults are easier to trigger in some versions then in others, but I can`t tell why for sure.

When I do following list of actions with FreeCAD:

  1. open test3.FCStd
  2. open Placement dialog of Body
  3. switch to Euler angles and adjust angle with scroll wheel (afterwards don't touch the hierarchy or adjust anything until step 7)
  4. open another model (test4.FCStd) without closing Placement dialog
  5. close test3.FCStd
  6. closing of test4.FCStd may sometimes also be needed when the bug does not manifest after step 7
  7. adjust Euler angle in Placement dialog (preferably with a quick mouse wheel spin, bug may be related to quantity of events generated)
  8. observe a Segmentation fault

Hopefully information below will be useful to debug this.

With FreeCAD 0.20.2, Libs: 0.20.2R:
