  I also got the error using Xnest.  It seems that 
doOpenFont() function of dixfonts.c returns AllocError
(line 327):

    if (!pfont->fpe)
        pfont->fpe = fpe;
    pfont->refcnt++;
    if (pfont->refcnt == 1) {
        UseFPE(pfont->fpe);
        for (i = 0; i < screenInfo.numScreens; i++) {
            pScr = screenInfo.screens[i];
            if (pScr->RealizeFont)
            {
                if (!(*pScr->RealizeFont) (pScr, pfont))
                {
                    CloseFont (pfont, (Font) 0);
                    err = AllocError;
                    goto bail;
                }
            }
        }
    }

  But I don't know the detail of this code...
