when sending the image from one class to another class application is crashing..


Code..
Qt Code: 
  1. if(http_id == id && http->lastResponse().statusCode() == 200)
  2.     {
  3.         QPixmap image;
  4. QCache<QString,QPixmap>imageCache;
  5.  
  6.         QByteArray imagedata = buffer->data();
  7.         image.loadFromData(imagedata);
  8.  
  9.             imageCache.insert(requestByEntry.key(id),&image);
  10.           Form f;
  11.         f.set(*imageCache[URL]);
  12.         buffer->close();
  13.     }

Qt Code: 
  1. void Form::set( const QPixmap image)
  2. {
  3.         m_ui->label->setPixmap(image);
  4.         this->show();
  5.  
  6. }
