This is solved when using batik 1.6, which version 1.1 of the plugin depends on.
This is an awt error message (awt is used by batik for the conversion), which
doesn't allow images with a width and height of zero.
So you currently HAVE to specify the size of the svg image. In the root svg element add the
attributes width and heigth. If you have some ideas that can automatically find the size,
let me know.
