This is not a bug, it is a feature.

http://developer.gnome.org/doc/API/2.0/glib/glib-Key-value-file-parser.html#GKeyFile

Citing: The GKeyFile struct contains only private fields and
should not be used directly.

Not only you should not, but you cannot (unless you copy the
definitions to your sources, which obviously breaks badly
every time these internal structures are changed in GLib).
As a side effect you cannot declare GKeyFile variables, only
pointers to GKeyFile -- not that you could correctly
initialize such a variable anyway.
