I have been looking at some large SVG symbol files from IAN and having trouble with ungrouping them. I can get down to individual symbols and then I get stuck.

A typical case is an SVG image of a fish. This opens in Inkscape 0.42 readily and when selected shows "Group of 1 object". When I try and ungroup it it goes to "Clone of: Group of 1 object" and I don't get any further. Obviously I want to ungroup it to manipulate the image. It has colours, gradients and maybe transparencies.

I can save it as a png and use it that way but I want to retain and use it in vector format. Any suggestions on getting it ungrouped?
