Comment 6 for bug 1001724

OK, I have reverted r11370 in lp:inkscape r11386. This seems to fix the bug for me. Because changing SPCanvasItem and its subclasses to GObject will be a fairly intrusive process (and will no doubt involve a lot of fiddling!), I think it'll be easier to work in a branch over a few days rather than to keep track of numerous iterations of patches.

Maybe I'll work on some easier/safer bits first!
