Reproducibility: 100%

I found a crash.

- Steps to reproduce
  - Open a new drawing
  - import `gears.dxf`
  - move the gear drawing to anywhere (I just slightly drag it)
  - On keyboard do Undo (CTL-Z) to put the object back to the starting point
  - On keyboard do Undo a second time (CTL-Z) removes the imported file
  - On keyboard to Redo (SHIFT-CTL-Z) and the app will crash with the attached stack trace.

This is the gear demo from the [DXF / DWG wrong paths](https://discourse.shapr3d.com/t/dxf-dwg-wrong-paths/10820) thread.
