Awesome!  I was always wondering how to identify these.  The find
command does not detect these files on my Linux machine (Mageia 3),
but I have fixed these based on the details you posted:

http://article.gmane.org/gmane.science.nmr.relax.scm/19463

These would be because the icons come from a 3rd party (directly from
the NESSY sources or from Bruker with permission), and they must have
been broken at the source.  It's a bit ridiculous that the libpng
people have decided to not read these files any more rather than have
a transition or depreciation period whereby strong warnings are given!
 Oh, I have also fixed some serious issues with the
sample_scripts/relax_disp/R1rho_analysis.py script which I plan to
release in the next 3.1.1 relax version sometime in the future.  Maybe
you are interested:
