i don't know what program you're using to view kml files, but the 
following works for me if i drop the url onto google-earth:


import sys, os
from PyQt4.QtCore import Qt, SIGNAL, QMimeData, QUrl
from PyQt4.QtGui import (
     QApplication, QTableWidget, QTableWidgetItem, QDrag,
     )

class Window(QTableWidget):
     def __init__(self):
         QTableWidget.__init__(self, 1, 1)
         self.setEditTriggers(QTableWidget.NoEditTriggers)
         self.connect(self, SIGNAL('itemPressed(QTableWidgetItem*)'),
                      self.handleItemPressed)
         kmlfile = os.path.join(os.getcwd(), 'test.kml')
         self.setItem(0, 0, QTableWidgetItem(kmlfile))

     def handleItemPressed(self, item):
         if app.mouseButtons() == Qt.LeftButton:
             drag = QDrag(self)
             data = QMimeData()
             data.setUrls([QUrl.fromLocalFile(item.text())])
             drag.setMimeData(data)
             drag.exec_()


if __name__ == "__main__":
    app = QApplication(sys.argv)
    win = Window()
    win.show()
    sys.exit(app.exec_())
