multiple selected nodes, transformations revert when moved (rev >= 9985)

[Cojnel]

Tested with r12960 (default preferences) on linux mint 15 32bit.
It does not happen in v0.48.4 r9939.

Draw a path with at least 2 nodes,
pick the node tool,
select more than one node,
turn on show transformation handles,
make one transformation with a
scale/rotate or skew handle,
drag one of the selected nodes,
the nodes snap to the position
they had when they were first drawn.

If two or more transformation are performed,
then the nodes snap to the position they had
before the last transformation.

The center of rotation seams to keep the position
it got after the transformation when the nodes revert,
the same thing happens to the node handles.

Reproduced with r12964 on OS X 10.7.5.

- also reproduced with oldest archived build on this computer (r10795),
- not reproduced with stable 0.48.4 (r10007)

Based on tests with really old archived builds (compiled 2010 on Mac OS X 10.5.8, run on OS X 10.7.5):
- not reproduced with 0.48+devel rev <= 9983,
- reproduced with 0.48+devel rev >= 9987;
it seems possible that this regression is related to the changes for in rev 9985:

@Diederik - any chance you could take a look whether there's an easy fix for this bug?
