Your problem may be real, but your analysis is wrong:

$ ldd /usr/lib64/libgdk_pixbuf-2.0.so.0.2300.3 | grep png
	libpng12.so.0 => /usr/lib64/libpng12.so.0 (0x00000039ddc00000)

Hi! Analysis was provided by the kind people on the #gimp channel. What extra data would you need? 

Or are you just saying that gdk-pixbuf2 has png support. If so how can I test that?

Thanks a lot.

Comment 3 Matthias Clasen 2011-05-03 13:54:53 UTC

do what I did:

 ldd /usr/lib64/libgdk_pixbuf-2.0.so.0.2300.3 | grep png

that shows whether gdk-pixbuf is linked against libpng

then maybe

gvfs-info <your alleged png file>

to see what gvfs thinks its mime type is

thanks for the help. I did that (I'm using 32bit) and got confirmation on #gnome-shell support was enabled. 

I'll continue exploring elsewhere then. Thank you very much.
