I think this bug is more than a problem with the flow text.
I made a project with Inkscape and when I tried to print it I saw the black boxes. Triying to remove them I took the texts and made the "suv (suv-lp)" protocol but nothing changed.
I have isolated a sample copying it and there is no word "flow" on the svg file and everytime I try to print it on a pdf, the black boxes appears again.
