Great! Is it possible for you to provide a patch before feature freeze for 0.9 
(Monday 16 July)?

Qt-4.3.0 provides support for SVG export with QSvgGenerator. It's a subclass 
of QPaintDevice, so straightforward to use. And according to trolltech, this 
export should be much better now (but I did not test it). 

I'm in favour of keeping the current SVG export with Q3Picture and warning (if 
this is still possible with the ported print composer). People may already 
use that feature and, regarding the developments in Qt4.3, I don't think we 
need to drop that feature in the long run. When qgis moves to qt4.3 as 
minimum version, we may switch to QSvgGenerator and remove the warning.

cheers,
Marco
