I used the gnome.vfs.monitor_add() method:

            fname = self.getServiceLogFullPath(service)
            fi = gnome.vfs.get_file_info(fname)
            self.position[service] = fi.size - 1
            source = gnome.vfs.monitor_add(fname, gnome.vfs.MONITOR_EVENT_CHANGED, self.addData, service)

then my handler:
    def addData(self, monitorPath, infoPath, eventType, service):
        fname = self.getServiceLogFullPath(service)
        source = open(fname, 'r')
        pos = self.position[service]
        source.seek(pos, 0) # put the pointer at the right place
        data = source.readline()
        iter = self.buffer.get_end_iter()

	...

There is probably a better way to handle the file position, etc, than
the way I did it.
