  Maybe it is a hack, but from yet unreleased gBill under development:

#ifdef DEBUG
#define dbg(x) x
#else
#define dbg(x)
#endif

jmp_buf jumpbuffer;
char isinit;

static void gdk_recovery(void)
{
        dbg(printf("gdk_recovery!!!\n"));
        if (isinit) {
                dbg(printf("already inited/failed\n"));
                return;
                }
        longjmp(jumpbuffer,1);
}

void init_that_mess(int *argcp,char ***argvp)
{
        if (isinit||setjmp(jumpbuffer)) {
                dbg(printf("failing...\n"));
                isinit=1;
                return(FALSE);
                }

        dbg(printf("gtk_init...\n"));
        atexit(gdk_recovery);
        gtk_init(argcp,argvp);
        dbg(printf("gtk_inited.\n"));
        isinit=2;
        return(TRUE);
}
