12 bits tif image issue with skimage 0.5dev

[jip]

Dear all,
I update skimage to 0.5 dev on my ubuntu box. ipython startup gives:
Imported NumPy 1.3.0, SciPy 0.7.2, Matplotlib 0.99.3 + guidata 1.2.5, 
guiqwt 2.0.8.1
Type "scientific" for more details.
>>> import skimage
>>> skimage.version
<module 'skimage.version' from 
'/usr/local/lib/python2.6/dist-packages/scikits_image-0.5dev-py2.6-linux-i686.egg/skimage/version.pyc'>

A 12 bits tif image when loaded with skimage do not behave like the same 
image loaded with an other library (readmagick, mahotas), as shown above. 
When a 8 bits png image is loaded, the differences (orientation, 
saturation) vanish.

In a previous message Neil Yager said that the issue was fixed<https://groups.google.com/forum/#%21topic/scikits-image/JSvqMzOgTEE>. 
What should I do to fix the problem on my machine?
Thank you.

Jean-Patrick
