segfault in qt4-libs 4.6.1

[Sverre Froyen <sverre%viewmark.com@localhost>]

Hi,

I just upgraded pkgsrc on my laptop (running NetBSD current amd64) and I 
noticed that amarok would no longer build.  I've tracked the problem down to 
what looks like an error in qt4-libs-4.6.1nb2.  The following program

#include <QtCore/QCoreApplication>
#include <QtScript/QScriptEngine>

int main(int argc, char **argv)
{
    QCoreApplication app( argc, argv );
    QScriptEngine engine;
}

built with

g++ -I/usr/pkg/qt4/include  t.cc -L/usr/pkg/qt4/lib \
-Wl,-R/usr/pkg/qt4/lib -lQtScript

results in a segfault:

Program terminated with signal 11, Segmentation fault.

#7  0x0000000000400b42 in main ()

In addition, my current version of amarok segfaults on startup.

I'll try to make some headway on this later but if, in the meantime, somebody 
has a fix or a suggestion, I would be most happy to test it.
