I have a qgis plugin (c++) that adds a map tool inherits from QgsMapTool. My tool does nothing, juste I can activate my tool by triggering. I test my plugin in Qgis 2.4; when I activate my tool the I passed to another tool Qgis crash and write a minimum dump file.

this is the C++ code:
MapToolAdvancedEditPolygons::MapToolAdvancedEditPolygons( QgisInterface *ptInterface )
: QgsMapTool( ptInterface->mapCanvas () )
, m_ptInterface ( ptInterface )
{
}
MapToolAdvancedEditPolygons::~MapToolAdvancedEditPolygons()
{
}
I initialised my plugin as below:
void GeoAdvancedEditTool::initGui ()
{
m_ptAdvancedEditAction = new QAction ( QIcon ( ":/geoadvancededittool/images/AdvancedEditAction.png" ), tr ( "advanced edit polygons tool" ), this);
m_ptAdvancedEditAction->setCheckable ( true );
m_ptAdvancedEditAction->setActionGroup ( m_ptInterface->actionMoveFeature()->actionGroup() );
m_ptInterface->digitizeToolBar()->addAction ( m_ptAdvancedEditAction );
connect( m_ptAdvancedEditAction, SIGNAL( triggered() ), this, SLOT( advancedEditActivated() ) );
m_ptMapToolAdvancedEditPolygons = new MapToolAdvancedEditPolygons( m_ptInterface );
m_ptMapToolAdvancedEditPolygons->setObjectName( "GEOAdvancedEditPolygonsTool" );
m_ptMapToolAdvancedEditPolygons->setAction( m_ptAdvancedEditAction );
m_ptAdvancedEditAction->setEnabled(true);
}
void GeoAdvancedEditTool::advancedEditActivated()
{
m_ptInterface->mapCanvas()->setMapTool( m_ptMapToolAdvancedEditPolygons );
m_ptInterface->mapCanvas()->setCursor( QCursor( Qt::CrossCursor ) );
}
I don't understand why Qgis crash!
