I tried to use this:
<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
   <mime-type type="application/x-virtualbox-vbox">
      <comment>VirtualBox Machine Definition</comment>
      <comment xml:lang="en">VirtualBox Machine Definition</comment>
      <glob pattern="*.vbox"/>
      <icon name="virtualbox-vbox"/>
   </mime-type>
   [...]
as an example.

/usr $ find . -iname "virtualbox-vbox.png"
./share/icons/hicolor/16x16/mimetypes/virtualbox-vbox.png
./share/icons/hicolor/96x96/mimetypes/virtualbox-vbox.png
./share/icons/hicolor/48x48/mimetypes/virtualbox-vbox.png
./share/icons/hicolor/72x72/mimetypes/virtualbox-vbox.png
./share/icons/hicolor/32x32/mimetypes/virtualbox-vbox.png
./share/icons/hicolor/256x256/mimetypes/virtualbox-vbox.png
./share/icons/hicolor/128x128/mimetypes/virtualbox-vbox.png
./share/icons/hicolor/64x64/mimetypes/virtualbox-vbox.png
./share/icons/hicolor/24x24/mimetypes/virtualbox-vbox.png

so I tried <icon name="freeplane"/> (and <icon name="freeplane.png"/>),
and put freeplane.png here:
/usr/share/icons/hicolor/32x32/mimetypes/freeplane.png
(I also tried to put the svg in hicolor/scalable/mimetypes/)

=> probably a (local?) problem with my nautilus? It seems to work in
konqueror (and on another computer with the same config it even works
with nautlius :-/)

=> does it make sense to create a bug report against nautilus
(I looked at the prefs but couldn't find anything :-/)?

Previously I only started a new nautilius window, but know I have
restarted the whole system (X is probably enough?).

That is really useful. Is there also a way to debug the icon locations?

Thanks and Best Regards,
