Hello Edward,

I came across another issue. A couple of the png's have broken IDAT
entries and won't be shown with latest libpng. As reference see this
mail http://comments.gmane.org/gmane.linux.gentoo.devel/85066.

I can trigger this when running "identify .....png"

 $ find -name "*.png" -exec identify '{}' \; > /dev/null
identify: iCCP: known incorrect sRGB profile
`./graphics/relax_icons/png/nessy.png' @
warning/png.c/MagickPNGWarningHandler/1830.
identify: iCCP: known incorrect sRGB profile
`./graphics/relax_icons/22x22/nessy.png' @
warning/png.c/MagickPNGWarningHandler/1830.
identify: iCCP: known incorrect sRGB profile
`./graphics/relax_icons/48x48/bruker.png' @

warning/png.c/MagickPNGWarningHandler/1830.
identify: iCCP: known incorrect sRGB profile
`./graphics/wizards/nessy.png' @ warning/png.c/MagickPNGWarningHandler/1830.


As a result those icons are missing in the GUI.

A simple fix is using the pngcrush tool with following command

pngcrush -fix -force old.png new.png


Regards,
Justin
