Stroke to path fails if path has no fill/stroke/marker

Summary:

The SVG file found here USA.svg when running stroke to path via the CLI throws an exception

Steps to reproduce:

When I run Inkscape from the CLI with this command (to convert paths to strokes) inkscape "in_file.svg" --export-plain-svg --batch-process --actions "EditSelectAll;StrokeToPath;FileSave" --export-filename "out_file.svg" (this is the input SVG https://jsfiddle.net/zoe6ayL3/), I get this error. This command works for other files I am testing it on.

Alternative:

• Open inkscape
• draw a rectangle
• Object to Path
• change fill to None
• unset stroke
• Stroke to path

What happened?

ERROR:/Users/Shared/work/6DxXS3HP/0/inkscape/inkscape/src/xml/repr-css.cpp:474:void sp_repr_css_change(Inkscape::XML::Node *, SPCSSAttr *, const gchar *): assertion failed: (repr != nullptr)

What should have happened?

No Exception should have been thrown
