I'm using svg files I downloaded from the openclipart.org as icons. They render fine under linux, but barf under windows. Interestingly, an svg I edited in inkscape works OK, so for now I'm going to try running all my icons through inkscape.

Here's the error:

(hsvg.exe:1952): GdkPixbuf-WARNING **: Cannot open pixbuf loader module file ‘C:\PROGRA~1\SIDEEF~1\HOUDIN~1.124\hsvg\etc\gtk-2.0\gdk-pixbuf.loaders’: No such file or directory

sample svg file attached.
