3D Box moves away when i try to move a selection [Regression]

confirmed on Windows, Inkscape 0.47 pre0.
Attached is a simplified version with only 2 boxes.
- select and move the top box, it behaves as expected
- select and move the bottom box, it behaves as expected
- select and move both boxes and the bottom box moves twice as far as the top box
- the bottom box has the attribute sodipodi:type = inkscape:box3d
- this is a regression, it does not occur in 0.46

perhaps to clarify :
- if you create two 3D Boxes, select them both and move them both, then there is no problem.
- if you now convert one box using Path->Object to Path, and then select both and move both, then there is a problem.

Yes is true.
This problem is between 3D boxe and a group of object:
Try to:
- Create a 3D boxe
- Then draw some object (cicle, square,...) on the stage and group them
- Now select both group and boxe
try to move the selection: the problem appear

on my machine this bug appears some time between 0.46 release in April1, 2008, and Windows nightly build of June 27, 2008.

Also, the bug shows up only on the mouse release event. So, for example, select all objects, drag them all, and they all move together, but on the mouse release, the 3D Box makes the extra unwanted move.

Also, the group of objects which is not a 3D Box has a transform:translate attribute, which appears to come from the dragging operation, the 3D Box does not have this attribute.

Inkscape 0.47pre1 r21720:

1) create a 3dbox,
2) duplicate it
3) move the duplicated box to the side
4) select both 3dboxes and move them
5) when the mouse button is released, the duplicated box jumps back on top of the first 3dbox

(repeated) console messages:
  Warning! Trying to remove unselected perspective from selection!

not reproduced with Inkscape 0.46, built Mar 30 2008

@suv: I try to follow your instruction but i don't see this problem (Inkscape 0.47 pre0 ubuntu). What abuot you alvin?

Instead, reading the list of relatend bugs, i found that the 3D box stamping problem affects mee too.
I made some attemps and one is very strange:
-create a 3dboxes
-create circle (or someone else)
-group them
-select the group and without release the button press space several times moving the selection

the 3d boxes duplicated are all in the same place

Today I can't consistently reproduce the 'jumping back to the original' case myself.

If I create two 3dboxes, deselect all, then select the second one and follow the steps 2-5 in comment 6, most of the time I can reproduce it, but it happens erratically - at least I could not figure out a reasonable pattern.

Better stick to the case where the group with a 3dbox and another object reveals the bug when being moved.

Can you confirm this behavior? (tested with Inkscape 0.47pre1, OS X 10.5.7)

1) open Alvin's http://launchpadlibrarian.net/29221428/2boxes.svg
2) 'Select all' or 'Ctrl + A'
3) 'Copy' or 'Ctrl + C'

Result: 3dbox moves away when the selection is copied to the clipboard, no mouse event involved.

Yes i confirm you this behavior.

After press 'Ctrl + C' try to rotate the selection
Result: Inkscape crashes....(inscape 0.47 pre0 ubuntu 9.04)

the crash is confirmed on Windows XP when I try to rotate the whole selection after a copy. Exit message not very interesting :

Emergency save activated!

Crash reproduced with Inkscape 0.47pre1 r21720, built Jul 20 2009 on OS X 10.5.7
attaching gdb backtrace & crash.log

This should be fixed in bzr rev. 8911. I cannot reproduce the crash mentioned in comment #11 but it doesn't seem to be specifically 3D box related (telling from the backtrace in comment #14), so I'm closing this. Any further issues should be reported in a new bug report.
