Krita freezes and crashes to desktop after, while using the Magnetic Selection tool, creating a single anchor and dragging it.

STEPS TO REPRODUCE
1. Select the Magnetic Selection Tool.
2. Create a single anchor.
3. Drag that anchor anywhere.
4. At this point, the application has froze and it eventually silently crashes to desktop.

OBSERVED RESULT
Krita freezes once the anchor is dragged and eventually crashes to desktop.

EXPECTED RESULT
No freeze/crash.
