[Kde-bindings] Plasma crash

[David Palacio]

I get this crash with Plasma::WebView but not with Qt::WebView. Is
this reproduceable?

Testcase:

require 'plasma_applet'
about = KDE::AboutData.new(
        'irb_kapp', # app internal name
        'irb_kapp', # translation catalog name
        KDE.ki18n( 'IRB KApp' ), # name to be displayed
        '1.8.7', #version
        KDE.ki18n( 'Kuick IRB Application' ), #description
        KDE::AboutData::License_GPL_V3, #license
        KDE.ki18n( '(c) 2008 you' ) # copyright statement
                                    ) #AboutData
KDE::CmdLineArgs.init(ARGV, about)
KDE::Application.new
Qt.debug_level = 2
w = Plasma::WebView.new
#w = Qt::WebView.new
network_access_manager = w.page.networkAccessManager
