Crash on Inverse Clipping an object with its clone

Steps to reproduce:

• open Inkscape
• create an object
• clone it
• select both
• Object > Clip > Set Inverse Clip

What happened?

Inkscape crashes with: inkscape_debug_trace_2019.09.12.02.04.53.txt

What should have happened?

Not sure. Clipping an object with a clone of itself (for normal clips) doesn't work. So maybe: nothing? No crash, at least.

Inkscape Version and Operating System:

• Inkscape Version: 1.0beta0 (0a78936f89, 2019-09-11)
