Do other gtk+ programs work correctly with loading images on your
machine?
At this point, if you have the ability, i'd say port your example code
to C and verify that the C program still can't load the images.
If the C program can't load the images, that means that your gtk+ is
broken somehow, and the bug report goes to gnome bugzilla.
If the C program can load the images, then something is wrong with
your setup at runtime. Are the gdk-pixbuf loader modules being picked
up correctly? (I don't know how to tell on windows; on linux i'd use
strace.)
On further inspection of the gtk+ source, it looks like if there are
no builtin loader modules, gdk-pixbuf will scan the loader config file
to get the list spewed back by gdk_pixbuf_get_formats(); but this may
not reflect whether the modules can actually be loaded. So there may
be an issue with the loader module dlls not being in a path that you
can find at runtime.
