VirtualBox spamming journal logs with:  Qt WARNING: libpng warning:
iCCP: known incorrect sRGB profile

Problem

Some changes in libpng 1.6+ cause it issue warning or even not work
correctly with the original HP/MS sRGB profile. You'll notice this in
stderr:

libpng warning: iCCP: known incorrect sRGB profile

The old profile uses a D50 whitepoint, where D65 is standard. This
profile is not uncommon, being used by Adobe Photoshop, although it
was not embedded into images by default.

Solution

The simplest solution is simply to remove the embedded profile from
your image. This can cause a slight shift in color *IF* have have a
properly calibrated system, monitor, and software. If you really need
it (say for a print shop), you can alternatively embed a different
color profile. If this applies to you, you probably have the profiles
you need already.

GIMP

To remove the embedded profile, go to Image > Mode > Assign Color
Profile and set it to RGB workspace(sRGB built-in) To change the
embedded profile, go to Image > Mode > Convert to Color Profile where
you can choose a profile you already have loaded or load a new one
from disk.

ImageMagick

To remove the embedded profile, just run % convert -strip <input
filename> <output filename>
