rearranging Layers may shift object location

Bug Description

while rearranging several layers in a large complex drawing, I found, that in my case the objects on the moved layers where geometrically shifted. I deleted most of the original drawing, so only the small file still containing the bug remains.
Please see attached file: Layer_rearrange_bug.svg

It only contains two layers on the most top level, called Layer_A and Layer_B, while Layer a has two sub layers.
Except of Layer_B, all other Layers doesn't contain any drawing item.

If you now drag and drop in the Layer Window the Layer_B in-between the sub layers of Layer_A, than the red square will be shifted.

InkScape Version 0.48+devel_r11717_lp988601
Win7, 64 bit, 8 GB RAM

Happens with inkscape_r12378-201306161123 too.

The bug is confirmed on trunk branch.

Moving Layer_B to Layer_A or it's sub-layers causes the transformation because Layer_A has this translate:


It should probably apply the reverse offset somehow, making sure to adjust for the transformations of any parent layers it's being moved from too.

@Mc - with Inkscape 0.91+devel rev >= 14142, working with 3dboxes triggers these kinds of warnings repeatedly (also mentioned in bug #1478137):

** (inkscape:74243): CRITICAL **: virtual void Inkscape::XML::SimpleNode::changeOrder(Inkscape::XML::Node *, Inkscape::XML::Node *): assertion 'child != ref' failed

Any chance you could take a quick look at how they relate to the changes committed to fix this report, and whether they need to (or could be) addressed?
