Seg Fault in Valgrind using QtWebKit

Depending on the machine, I get a segfault running the following code in or sometimes out of valgrind. The backtrace points to QImage::read(), the same as issue 27032, although I can't get a valid backtrace on my current machine, as it only segfaults in valgrind. It seems to happen in jpeg_CreateDecompress(). Tough to find where it is causing problems without being able to use valgrind and gdb.

#include <QApplication>
#include <QMainWindow>
#include <QtWebKit>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QWebView *view = new QWebView();
view->load(QUrl("http://maps.google.com"));
view->show();

return app.exec();
}
