As for my _part_ of the bug, I figured out, that it is transformation matrices of gradients that cause it. to give you an example:
<linearGradient inkscape:collect="always" xlink:href="#linearGradient3813" id="linearGradient4074" gradientUnits="userSpaceOnUse" gradientTransform="matrix(3.786847e-6,1.045166e-6,-1.045166e-6,3.786847e-6,-53.0238,-21.8569)" x1="37179696" y1="16832558" x2="19937692" y2="5225754" />
without the gradientTransform the display is just like in inkscape, but obviously it's not the correct dislay.
