[QScintilla] QsciApis crash

[Gedalia Pasternak]

Is anyone else seeing a crash or memory scribbles when the QSciAPIs object
is destroyed?

The following code is bringing down my app when I destroy the widget
(running qt3, with quite a number of api entries.)

QWidgetCodeEditor::QWidgetCodeEditor(QWidget *parent, const char *name,
WFlags f ) :
      QsciScintilla(parent, name,f)
{
    m_lua_lexer = new bdiLexerLua();
    m_lua_apis  = new QsciAPIs(m_lua_lexer);
    m_lua_lexer->setAPIs(m_lua_apis);

    m_perl_lexer = new QsciLexerPerl();
    m_perl_apis  = new QsciAPIs(m_perl_lexer);
    m_perl_lexer->setAPIs(m_perl_apis);

    m_initted = 0;
}


/****************************************************************************/
QWidgetCodeEditor::~QWidgetCodeEditor()
{
   m_perl_lexer->setAPIs(NULL);
    m_perl_apis->cancelPreparation();
    delete m_perl_apis; m_perl_apis = NULL;

    m_lua_lexer->setAPIs(NULL);
    m_lua_apis->cancelPreparation();
    delete m_lua_apis; m_lua_apis = NULL;

    delete m_lua_lexer; m_lua_lexer = NULL;
    delete m_perl_lexer; m_perl_lexer = NULL;
}
