Krita crash log

SUMMARY
Crash when using Comic Panel Editing Tool

STEPS TO REPRODUCE
1. Make a vector layer, and draw a circle with the Ellipse Tool
2. Switch to Comic Panel Editing Tool
3. In the Tool Options docker, select the rightmost icon. (Looks like a square with a single line inside of it)
4. Use the tool on the circle

OBSERVED RESULT
Krita will either crash, or give you the following message:

Krita has encountered an internal error:

SAFE ASSERT (krita): "segment.length() == 2" in file /builds/graphics/krita/libs/global/kis_algebra_2d.cpp, line 1907

Ignoring the message then results in a crash.

EXPECTED RESULT
No crash.
