This looks like a bug in some recent libpng, but _before_ 1.2.8

Most likely this libpng is not the one actually used, as pdftex is
normally compiled with libraries statically linked to it (e. g. if you
uninstall the libpng from SuSE, it should still run...). Maybe recompile
pdftex with libpng-1.2.8 or pick a recent pdftex binary, e. g. 1.21a,
which should contain 1.2.8. If you already have this, and it still
crashes, then please put the problematic .png online for checking.
