Crash in QWebView - qt

Question

My application contains a class which inherits QWebView. The problem is that I get a crash every time I try to type something in this view! Here's my code :
void QViewSupport::setupSupport(QWidget * widget)
{
QUrl startURL = QUrl("http://www.google.fr");
load(startURL);
}
So basically whenever I try to type something in the google search bar, it crashes at the first character...
Here's the output :
ASSERTION FAILED: ICU could not open a break iterator:
U_MISSING_RESOURCE_ERROR (2)
U_SUCCESS(openStatus)

Am I missing something? I searched the Internet and couldn't find something close to this problem. Thanks in advance if you have the solution!
Edit : As asked, here's the class :
class QViewSupport : public QWebView
{
Q_OBJECT
public:
QViewSupport(QWidget *parent);
~QViewSupport();
private:
void setupSupport(QWidget *Form);
};
And in the .cpp file :
#include "qviewsupport.h"
QViewSupport::QViewSupport(QWidget *parent)
: QWebView(parent)
{
setupSupport(this);
}
void QViewSupport::setupSupport(QWidget * widget)
{
QUrl startURL = QUrl("http://www.google.fr");
load(startURL);
}
QViewSupport::~QViewSupport()
{
}
Edit : The call to this function is done in Setup.cpp (see below), and pViewSupport is a private member define in the Setup class : QViewSupport* pViewSupport;.
Setup::Setup(QWidget *parent)
: QDialog(parent)
{
setupUi(this);
}
void Setup::setupUi(QWidget * widget)
{
// plenty of other things
pViewSupport = new QViewSupport(this);
// same
}

Ok, the problem came from the ICU dlls from Qt, I just replaced them and it worked.
