That is one of the problems. This is already fixed in Fritzing but apparently didn’t make it into 0.9.4.
The other problem is that Inkscape puts the font family name (Droid Sans) into the SVG, but for some reason Fritzing thinks that it needs to be the font file name (DroidSans). I didn’t really 100% understand the code behind this, but a test with the Parts Editor shows that converting all font family entries to DroidSans will give no errors when importing a SVG.
What Fritzing needs to do is do this conversion by itself, by mapping the font family name to the file name for Droid Sans. Or check if that assumption, that it needs to be the font file name, is still true.
