I do not see the problem here, Using a font common to all 'Albertusbold' in my ~/.fonts folder
Tried a plain SVG, an Inkscape SVG then again after applying 'Clean Document' all open up in Gimp 2.8.18 showing the correct font: http://imgur.com/jiHgJjn even put in a hard space (U+00A0) for good measure.
FWIW
Kubuntu 16.04
Inkscape from https://launchpad.net/~inkscape.dev/+arc...ntu/stable ver 0.92
Cairo version 1.14.6-1
rSVG ver 2.40.13-3
