I asked this in kde-devel, but maybe here is a better place.

Hi,

Take a look at qt-copy/tools/designer/designer/images/designer_newform.png. I
don't know for you, but for me nothing will read it. I've updated libpng to
the latest 1.2.5 to make sure. In trolltech.com's tarball, that png file is
not the same, and loads correctly.

For example, with gimp:
[nomis80 at Porti images]$ gimp designer_newform.png
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng warning: Ignoring bad adaptive filter type
libpng error: incorrect data check

With display (from ImageMagick):
[nomis80 at Porti images]$ display designer_newform.png
display: incorrect data check (designer_newform.png).

And with everyone's favorite:
kviewviewer: open local file
/usr/lib/qt/tools/designer/designer/images/designer_newform.png
kviewviewer: [virtual bool KViewViewer::openFile()]  load from file:
/usr/lib/qt/tools/designer/designer/images/designer_newform.png

There are other files in that directory that won't load. So, what's the
 catch?
