Qt 4.3.0beta svg text segfault

[mr.costa]

My Qt 4.3.0 beta in linux crashes when rendering a svg with text. This is gentoo amd64.

Attached there is a minimal testcase. The backtrace is:

main.cpp is:

// #include <QCoreApplication>
 
#include <QPainter>
#include <QImage>
#include <QSvgRenderer>
#include <QDebug>
 
int main( int args, char** argv) {
	QSvgRenderer svg( QString("test.svg") );
	QImage img( 128, 128, QImage::Format_ARGB32 );
	img.fill( 0 );
	QPainter p( &img );
	svg.render( &p );
	QImage img2 = img.convertToFormat(QImage::Format_ARGB32, Qt::AutoColor| Qt::AvoidDither);
	img2.save( "test.png" );
}

// #include <QCoreApplication>

#include <QPainter>
#include <QImage>
#include <QSvgRenderer>
#include <QDebug>

int main( int args, char** argv) {
	QSvgRenderer svg( QString("test.svg") );
	QImage img( 128, 128, QImage::Format_ARGB32 );
	img.fill( 0 );
	QPainter p( &img );
	svg.render( &p );
	QImage img2 = img.convertToFormat(QImage::Format_ARGB32, Qt::AutoColor| Qt::AvoidDither);
	img2.save( "test.png" );
}

To copy to clipboard, switch view to plain text mode 

Is it for me alone? Should I report this? where?

Thanks for reading.
