Different code is used to get the font when using GTK+ 1.2[.x] and 2.x.

The 1.2[.x] code does

    h_dc = CreateDC("DISPLAY", NULL, NULL, NULL);
    if (h_dc == NULL) return 1;
    h_font = GetStockObject(DEFAULT_GUI_FONT);
    if (h_font == NULL || !SelectObject(h_dc, h_font)) {
        DeleteDC(h_dc);
        return 1;
    }
    len = GetTextFace(h_dc, NAME_BUFFER_LEN, name);
    if (len <= 0) {
        DeleteDC(h_dc);
        return 1;
    }
    if (!GetTextMetrics(h_dc, &tm)) {
        DeleteDC(h_dc);
        return 1;
    }
    pix_height = tm.tmHeight;
    DeleteDC(h_dc);
    sprintf(fontspec, "-*-%s-*-*-*-*-%i-*-*-*-p-*-iso8859-1", name,
            pix_height);

and the 2.x code does

    if (SystemParametersInfo(SPI_GETNONCLIENTMETRICS, ncm.cbSize, &ncm, 
0)) {
        HDC screen = GetDC(0);
        double y_scale = 72.0 / GetDeviceCaps(screen, LOGPIXELSY);
        int point_size = (int) (ncm.lfMenuFont.lfHeight * y_scale);

        if (point_size < 0) point_size = -point_size;
        fontspec = g_strdup_printf("%s %d", ncm.lfMenuFont.lfFaceName,
                                   point_size);
        ReleaseDC(0, screen);
    }

The page on MSDN about SystemParametersInfo() doesn't seem to be saying 
anything to indicate that it doesn't work in pre-NT 5.0 systems.

It might, however, be an issue of the calls that GTK+ 2.x is using.
