Upon copying arrow ends of lines distort

[Nizamov Shawkat]

I can not reproduce the behavior beginning from the empty file, that's why an example svg file is attached.
My working file contains a several tilted rectangles and I believe that their existence somehow influence the behavior of lines with arrow ends. In attached file everything except the line with arrow is removed.

1) Open attached file. Center on a line.
2) Try to copy or move the line with arrow - look how arrow ending changes.
3) Try to create another tilted line with arrow ending - it is OK. Try e.g. to rotate it or copy it or move it and look what happens with arrow.

Inkscape 0.48.1 / ubuntu 11.04.

PS Sorry, if bug-report is another false.

Reproduced with Inkscape 0.48.1 and 0.48+devel r10118 on OS X 10.5.8 (i386)

Transforming - e.g. moving - the original (or a duplicate) or copy&pasting (which includes an implicit moving to the cursor position) applies the nested transforms of the parent groups to the marker(s).

Not sure what is correct according to the SVG spec (the initial rendering when creating the path inside transformed groups or having the transforms applied to the marker once the path is transformed).

Reproduced with Inkscape 0.46 and 0.47 too -> no regression.
