Hi Jorg,
Result: the new paths are now displayed properly but the logo is being 
displayed as well still. I checked the DOM tree and it's effectively 
gone there. With the next redraw (eg canvas resize or something) the 
logo disappears.

   I don't suppose you can reproduce this?
It happens every time.
   It sounds to me like a race condition are 2a/b done
together in the code or could the be done in different
threads (not update thread?) or something?
The removal code and the update code happen in the same updatemanager 
thread, nearly sequentially.

   I'm having a hard time understanding how you could possibly
get this result if 2a happened before 2b in the UpdateManger
thread.
There is some odd behaviour though, because even when i set the node in 
question to hidden before i remove it, it is still displayed. Only when 
i set it to hidden and don't remove it it is not displayed anymore.

Element logo = getSVGDocument().getElementById("logo");
if (logo != null) {
  logo.setAttributeNS(null, "visibility", "hidden");
  while (logo.hasChildNodes()) {
    logo.removeChild(logo.getFirstChild());
  }
// remove the logo
logo.getParentNode().removeChild(logo);
}
Regards
Jorg
