Well, maybe that's how it should work, but the "plasmoid lookup" code 
for SVGs is kinda broken.  It only ever worked if the Plasma::SVG was a 
direct child of the Applet object (which you can't do in QML), and I'm 
pretty sure it doesn't work at all now (there are two bits of code that 
do the "theme lookup", and the one that actually gets called first - via 
elementRect, IIRC - doesn't look in the plasmoid).

I had a look at fixing this, but couldn't determine a sensible way to 
find out what the plasmoid was from Plasma::SVG in the case of QML 
plasmoids.  Simply walking up the QObject parent tree doesn't work.

As a result, I end up using plasmoid.file to get the correct path to the 
SVG file.  I don't *think* that looks at the theme, though.  If it does, 
it doesn't appear to allow the theme to override the plasmoid file.
