        * app/xcf/xcf-write.[ch]
        * app/xcf/xcf-save.c
        * app/xcf/xcf.c: ported the fix for bug #101340 over from the stable
        branch.  Uses GError to report errors, unlike the stable version, which
        uses a pointer to gboolean.

        * app/xcf/xcf-seek.[ch]: check the return value of fseek and ftell for
        errors.  Return FALSE and set GError if an error is detected.

        * app/xcf/xcf-load.c: since the xcf-seek functions use GError now,
        added a NULL for the error parameter.  Added basic error checking
        on the return value of the xcf-seek functions.  In the future,
        changing xcf-load.c to use GError more completely should be
        considered.

        * POTFILES.in: mark the error messages added for translation
