Comment 4 for bug 516178

Confirmed on Windows XP, Inkscape 0.46, 0.47 and bzr rev. 9275. Blank python command box.
Also confirmed on Ubuntu 9.10, Inkscape 0.47 and bzr rev. 9288, Uniconvertor 1.1.4, but I also get an error message (and of course no command box...).
Exporting simple shapes (rectangles and ellipses) works well on both operating systems with all Inkscape versions.

Error message:
