Hello, I got this error when playing with a tiff image

Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/guiqwt/histogram.py", line 364, in set_full_range
    imin, imax = item.get_lut_range_full()
  File "/usr/lib/python2.7/dist-packages/guiqwt/image.py", line 488, in get_lut_range_full
    return _nanmin(self.data), _nanmax(self.data)
  File "/usr/lib/python2.7/dist-packages/guiqwt/image.py", line 190, in _nanmin
    return np.nanmin(data)
  File "/usr/lib/pymodules/python2.7/numpy/lib/function_base.py", line 1507, in nanmin
    return np.fmin.reduce(a.flat)
TypeError: cannot reduce on a scalar
