#### Summary:
As the title implies, Inkscape encounters an internal error, and the program terminates.
#### Steps to reproduce:
<!-- Describe what you did (step-by-step) so we can reproduce: -->
- open Inkscape.
- create an inverse clip of an object (a triangle with flat faces drawn with "Bezier and straight line" tool, in my case) and a path (from a cutted square outline, which is the same programmatically, because it gets converted I presume).
- save it as an SVG.
- re-open Inkscape, and load the svg file.
- release the clipped object.
#### What happened?
I have no idea what the errors are, it just straight up prompt me internal error, and then you just press the button to terminate the program.
#### What should have happened?
- the clip should have been released into the original paths, and an object (a triangle, in my case).
