Ok, I think I found out what is going on, with the single line text issue. The Text is actually all good.
What is happening, is, Inkscape is trying to close the loop, on the text.
Have a look at the attached dxf file, look at the letter "e", Inkscape closed the loop (joined the starting point, with the ending point).
The font I used was "Machine Tool Gothic", with no edits or hand tracing.
So, it does work, it just works toooo good...
