Thanks Mike, I figured it was a bug as well. In the meantime, I used much thinner paths around the edges so the rounded corners would not be so pronounced, and then fill the center with the bucket when I get tired of making paths.
I've logged this as a bug for investigation.
I have built several files in Inkscape. I have been using thick bezier curve lines to color the image. They look right in inkscape, but Vidoescripbe is rounding corners that I have set to be sharp corners in the file. Is there a work around for this?
