min-x min-y from viewBox are not interpreted when opening a svg

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open a svg file with min-x and min-y set in the viewBox attribute. 

What is the expected output? What do you see instead?
See pictures.

The first picture shows the Svg without the viewBox attribute.
Width="400" height="200".

The second picture shows the Svg with the viewBox attribute, correctly rendered
viewBox="100 100 200 100"

The third picture shows the svg with the viewBox and how it is rendered by 
svg-edit.

The last file is the svg image that I used.

In what browser did you experience this problem? (ALL, Firefox, Opera, etc)
ALL

In what version of SVG-edit does the problem occur? (Latest trunk, 2.5.1,
etc)
