Exporting a selection yeilds erroneous viewBox

Summary:

I have a simple SVG image with a single object. I can load it and save it without problems. However, if I select the object, and check "Export Selected Only" on the Export tab, I get an SVG with extremely large dimensions.

Steps to reproduce:

  • Start inkscape
  • Open path18.svg
  • Select the object
  • Navigate to the Export tab
  • Check "Export Selected Only"
  • Choose "Plain SVG:" and export.

What happened?

The exported SVG has a very huge viewBox, see attachment path1.svg.

What should have happened?

The exported SVG should have the same viewBox as the original.
