I found a crash.
- Steps to reproduce
- Open a new drawing
- 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.
Hopefully, you can symbolicate this:
