[Tobias Oetiker]

Hi Raimund,

the fix in r1439 ...

this is the minimal patch ...

--- src/rrd_graph.c     (revision 1438)
+++ src/rrd_graph.c     (working copy)
@@ -2951,8 +2951,13 @@
     PangoFontMap *font_map = pango_cairo_font_map_get_default();

     /* if we are lazy and there is nothing to PRINT ... quit now */
-    if (lazy && im->prt_c == 0)
+    if (lazy && im->prt_c == 0) {
+        info.u_cnt = im->ximg;
+        grinfo_push(im, sprintf_alloc("image_width"), RD_I_CNT, info);

         return 0;
+    }
     /* pull the data from the rrd files ... */
     if (data_fetch(im) == -1)
         return -1;
