For all self-compileros I attach a small helper program that is able to convert (most) svg/svgz to png in scratchbox.
The zipped project dir contains an ARM binary qsvg2png that belongs into PATH, needs libqt4 installed (of course only in scratchbox)
and a hardcoded replacement for navit/navit/xpm/navit_svg2png.

bank.svg, country_AD.svgz, country_AU.svgz, country_GS.svgz, country.svgz, country_SV.svgz and country_TR.svgz do still segfault :-/
