reproduced with Inkscape 0.47 and 0.47+devel r9410 on OS X 10.5.8
The bug exists also in the new node tool, but has slightly changed: while in 0.47 the selected nodes after undoing 'Insert new nodes' appear more randomly distributed on both sides of the previous selection of nodes, in 0.47+devel nodes of the adjacent segments in direction of the path (i.e. towards the end of the path) are selected after undoing.
