Paste selection with original+clone(s): Wrong placement between original and clones

[pRototype]

Affected Inkscape versions on WIndows 7 and Windows XP:
Inkscape 0.48.4 r9939
Inkscape 0.48+devel r12162

Have two elipses centered to each other. Grouping those two and make five clones.
Copy and pasting both the original and the clones at same time will most likely result in wrong placement of the clones in respect to the pasted original object.
Youtube video explain better than I do with my poor english:

I upload the affected svg file. It has being worked on many times, redone and saved as new file many times since the first version. Therefore I think I cannot recreate this behaviour by creating a brand new file.

The pasted clones are displaced due to the transform attribute of the parent layer group:

Workaround:
1) select the 6 objects, group them
2) add a new layer above the current one ('innhald')
3) move the group created in step 1 to the new layer ('Shift+PageUp')
4) on the new layer, ungroup the group
5) select all 6 objects, copy & paste

-> no more unexpected displaced pasted clones.

Bug #802053 “Operation on multiple cloned object gives odd results”
and lots of earlier reports about displaced objects, all triggered by clones not handling transforms on parent groups well (it's a known issue which can show up in various ways).

Reproduced with 0.91 r13725 and 0.91+devel r13925 on OS X 10.7.5.

[ Note to bug team: not addressed by recent commit r13924, in trunk with default template (mm) additionally affected by incorrect scaling of the pasted clone -> foe new tests in trunk, use 'default px' as template. ]
