Description

Trying to panelize this shape which I manually modified into a single piece, but kikit seems to think they're separated?

Steps to Reproduce

kicad_pcb file is at https://gist.github.com/idank/135c4e77218d9c83f3f2acf14279a467.

kikit panelize \
    --layout 'grid; rows: 2; cols: 2; space: 2mm' \
    --tabs 'fixed; width: 3mm' \
    --cuts 'mousebites; drill: 0.5mm; spacing: 1mm; offset: 0.2mm; prolong: 0.5mm' \
    --post 'millradius: 1mm' --debug 'trace: true;' \

There is a zero-length segment in your source file at the specified coordinates. If you remove it, everything works.

Nevertheless, KiKit should ignore such segments, however, there was a bug. This is fixed in a7873c2.
