Comment 2 for bug 1322527

I also tried going back to image #39 on mako and it seems broken there too.

#34 - works
#36 - works
#38 - broken
#39 - broken

So it broke in either #37 or #38. From http://people.canonical.com/~ogra/touch-image-stats/ we can see the changes:-

#37:-

ucf from 3.0028 to 3.0029

#38:-
