Tweak tool: crash attracting part of path between two circles

Summary:

Using "Attract parts of paths towards cursor" -tool between two circles (during testing both filled and only outlined circles could be used for reproducing) drawn relatively close to each other (~15mm) crashes the program. Exact steps for 100% guaranteed reproduction are not clear as of now. Our three member team* managed to reproduce the bug ~1/4 times.

*Only a school project team. Not experts.

Steps to reproduce:

• open Inkscape
• draw two circles (d=~80mm) close (~15mm) to each other roughly on the same level
• select both circles with selection tool
• pick the "Attract parts of paths towards cursor" -tool and click the space between the circles and drag up/down

What happened?

Program crashed

What should have happened?

Parts of the circles should've been dragged towards the cursor
