syste,. nonetheless, run the command below ( this may take a long time )

$ prelink --all

check for the presence of this file . i was unable to find this in
strace 
/usr/lib/gtk-2.0/2.4.0/loaders/libpixbufloader-png.so

If present, add the line below to "/etc/gtk-2.0/i386-redhat-linux-
gnu/gdk-pixbuf.loaders" as shown
---------------------------------------------------------
"/usr/lib/gtk-2.0/2.4.0/loaders/libpixbufloader-png.so"
"png" 1 "gtk20" "The PNG image format"
"image/png" ""
"png" ""
"\211PNG\r\n\032\n" "" 100
---------------------------------------------------------

If the above fails, re-install gtk2 package on system
from my system 
$ rpm -q --whatprovides /usr/lib/gtk-2.0/2.4.0/loaders/libpixbufloader-
png.so
gtk2-2.4.13-19
