Did you consider the type of SVG element you are trying to get the 
bounds from? In KBlocks for example I realized that in 4.3.0 the stroke 
was not taken into account when measuring the bounds. So in Inkscape for 
example if you had a 19pixel rect with a 1pixel stroke then QtSVG would 
consider that the width and height of the element were 19, and not 20 as 
shown in Inkscape.
I would look at the strokes first, and then the type of element (rect, 
or path for example.) Does converting to path solves anything?
To me, it looks like 4.3.1 Svg is broken. Or 4.3.0 was. Regresssions 
like this anyway really hurt our confidence in Qt, specially happening 
in such a minor release.
I think we need a direct channel with the TT guys that could help us 
understand what has changed, and what to do. Aaron, can you help with 
this particular issue?
