Also, my tests here using optipng 0.7.4 to detect damaged png files indicate
that only data/gdalicon.png in gdal-0.10.1 needs to be fixed.

optipng -nb -nc -np -fix data/gdalicon.png
** Processing: data/gdalicon.png
Warning: 
32x32 pixels, 4x8 bits/pixel, RGB+alpha
Recoverable errors found in input. Fixing...
Input IDAT size = 1964 bytes
Input file size = 2021 bytes

Trying:
  zc = 9  zm = 8  zs = 0  f = 0		IDAT size = 240
                               
Selecting parameters:
  zc = 9  zm = 8  zs = 0  f = 0		IDAT size = 240

Output IDAT size = 240 bytes (1724 bytes decrease)
Output file size = 313 bytes (1708 bytes = 84.51% decrease)

** Status report
1 file(s) have been processed.
1 error(s) have been encountered.
1 erroneous file(s) have been fixed.
