Qt webkit segmentation fault with pluginEnabled option

[victor]

I have the next problem:

I`m using webkit and qt 4.8.1 (qtbrowser demo). I have 'segmenation fault' with the next url http://ecommerce.aheadworks.com/magento-extensions/iphone-theme.html.

params:

- Window XP
- qt 4.8.1
- QWebSettings::PluginsEnabled

QWebSettings *defaultSettings = QWebSettings::globalSettings();
defaultSettings->setAttribute(QWebSettings::JavascriptEnabled, true);
defaultSettings->setAttribute(QWebSettings::PluginsEnabled, true);

any help would be appreciated

[victor]

For details:

I am using:


Windows xp SP3 (x86)
QtSDK version 1.2.1:


Qt libraries version 4.8.1
mingw:


binutils-2.19.1
mingwrt-3.15.2
w32api-3.13
gcc-core
gcc-c++-4.4.0
gmp-4.2.4
libiconv-1.13
mingw32-make-3.81
mpfr-2.4.1
pthreads-w32-2.8.0







Simple test example:

1. test.pro:


QT += webkit network
SOURCES = main.cpp


2. main.cpp



#include <QApplication>
#include <QtWebKit>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);

// settings
QWebSettings *settings = QWebSettings::globalSettings();
settings->setAttribute(QWebSettings::JavascriptEnabled, true);
settings->setAttribute(QWebSettings::PluginsEnabled, true);

//view
QWebView view;
view.show();
view.setUrl(QUrl("http://ecommerce.aheadworks.com/magento-extensions/iphone-theme.html"));

return app.exec();
}



I have the next error message after running of program:
