[Inkscape-user] Importing and saving

Hi, I'm having a little trouble in 0.40. I'm working with taking an SVG, importing another (which renders correctly on its own), and saving it. If I do that, the gradients in the imported SVG do not save correctly and show up various shades of gray. However, if I rechoose the gradient from the list (the same one that it already is), and resave it, it then renders correctly.

Is this a bug or expected behaviour?

Thanks, Andrew
