Hi all,

For some unknown reason, all lpes having theire own "addCanvasIndicators()" (namely lpe-knot and lpe-cpopyrotate) now crash inkscape whenever you try to edit with the node tool. Just in case someone is aware of some recent change in the code causing this, please make suggestions, it might save me some time trying to understand what is going on! ;-)

This is a crash in snapping code, so I'm ccing Diederik. Just draw a self-intersecting path with Pencil, ctrl+shift+7, choose Knot, Add, F2.
