That's weird, the log says errno is ENOTTY (25), which mean it should not reach
this error:

    if (v4l2_ioctl (v4l2object->video_fd, VIDIOC_ENUMINPUT, &input) < 0) {
      if (errno == EINVAL || errno == ENOTTY)
        break;                  /* end of enumeration */
      else {
        GST_ELEMENT_ERROR (e, RESOURCE, SETTINGS,
            (_("Failed to query attributes of input %d in device %s"),
                n, v4l2object->videodev),
            ("Failed to get %d in input enumeration for %s. (%d - %s)",
                n, v4l2object->videodev, errno, strerror (errno)));
        return FALSE;
      }
    }

Another thing I notice, is that in both 1.4 and master branch, this error is at
line 152, and the log you provided says it is at line 142. Are you really using
GStreamer 1.4.5 as reported here ? Have you made any modification to GStreamer
?
