Comment 49 for bug 722017

> Compilable patch attached.

Thanks - crash still reproducible, e.g.

0) rm -r ~/.config/inkscape
1) launch inkscape without arguments (empty new document)
2) draw a rectangle (defaults to flat blue fill)
3) open Fill&Stroke (Ctrl+Shift+F), change flat fill to linear gradient
3) copy & paste the rectangle (Ctrl+C, Ctrl+V) (gradient is forked with new ID)
4) switch to the gradient tool, select a gradient stop of the pasted rectangle
5) assign a different color to the selected gradient stop by clicking on a color swatch in the palette below the canvas
