    Default Qt webkit segmentation fault with pluginEnabled option

    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/mage...one-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

    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 Code: 
    1. QT       += webkit network
    2. SOURCES   = main.cpp
    To copy to clipboard, switch view to plain text mode 

    2. main.cpp
    Qt Code: 
    1. #include <QApplication>
    2. #include <QtWebKit>
    3.  
    4. int main(int argc, char *argv[])
    5. {
    6.     QApplication app(argc, argv);
    7.  
    8.     // settings
    9.     QWebSettings *settings = QWebSettings::globalSettings();
    10.     settings->setAttribute(QWebSettings::JavascriptEnabled, true);
    11.     settings->setAttribute(QWebSettings::PluginsEnabled, true);
    12.  
    13.     //view
    14.     QWebView view;
    15.     view.show();
    16.     view.setUrl(QUrl("http://ecommerce.aheadworks.com/magento-extensions/iphone-theme.html"));
    17.  
    18.     return app.exec();
    19. }
    To copy to clipboard, switch view to plain text mode 

    I have the next error message after running of program:

    I have "segmentation fault" in qtcreator debugger and the next :
