convert svg with <textPath> to png

Question

I am struggling to convert a svg to png. The file includes a <textPath> and is basically setup the same as this one here. I have installed imagemagick such that rsvg is/should be used for rendering of svg grafics.

$ convert -list delegate | grep -i svg
svg =>          "rsvg-convert" -o "%o" "%i"

$ convert -list format | grep -i svg
SVG  SVG       rw+   Scalable Vector Graphics (RSVG 2.40.18)

$ convert -version

Converting the SVG linked above using convert test-imagic.svg test-imagic.png results in the following image:

which is not what I am after.

How can I get such an svg converted to png or any other pixel graphic format?
