Crash on onMouseLeave...

Hi, I have a problem here, the TGB crash on onMouseLeave some times...
I found some topics about this bug here on GarageGames, but not a solution about it, anyone know something about it?!

here the bug line from t2dSceneWindow.cc file...

// We have to dance a bit to get onMouseLeave to work
   for( U32 i = 0; i < lastPickVector.size(); i++ )
   {
      t2dSceneObject* lastObject = static_cast<t2dSceneObject*>( lastPickVector[i] );
      if( !lastObject )
         continue;

      bool bFoundNew = true;
      for( U32 j = 0; j < pickVector.size(); j++ )
      {
         t2dSceneObject* object = pickVector[j];
         if(!object)
            continue;

         if( object == lastObject )
         {
            bFoundNew = false;
            break;
         }         
      }

      if( lastObject && lastObject->isProperlyAdded() && bFoundNew == true && lastObject->getUseMouseEvents() )
         lastObject->onMouseEvent( "onMouseLeave" , event, worldMousePoint );  // crash here
   }

Thanks
