Crash when canceling an operation (Ctrl+Z)

[Valentine A.]

Inkscape 0.92.2 2405546, 2018-03-11
Manjaro Linux 4.14.47-1-MANJARO

Reproduce:

Open Inkscape.
Create 2 simply shapes (circle).
Select two object and run Path > Difference.

When I want to cancel an operation Ctrl+Z - Inkscape crashed.

Sometimes not immediately apparent. Without performing other operations, you can return to the beginning with the keys Ctrl + Shift + Z and press again Ctrl+Z.

Thus, Inkscape falls when several simple operations are canceled.

This bug just popped up for me today after upgrading to the kernel listed above. The crash did not occur previously.

Duplicated the steps above and created a backtrace.

- reproduced on Windows 10, Inkscape 0.92.3 (2405546, 2018-03-11)
- draw 2 ellipses and perform Path->Difference
- draw two more objects to produce the attached file.
- then select one of the new objects and perform ctrl-Z until the original two ellipses reappear
- then do one more ctrl-Z and get crash with backtrace:
