[rrd-developers] RRDGraph Error in 1.5.0 and 1.5.1

[Bruce Morgan]

Using RRDtool version 1.4.7 I get a graph with the following command
(actually I use RRDs but no matter):
rrdtool graph /tmp/vic-crlt-pe1:25900_day.png --start -24h --end 1429773557
--width 820 --height 350 --title "vic-crlt-pe1 xe-0/0/3.201"  -a PNG

However in 1.5 I get the following:

*Unable to create graph: Not a valid vname: o687_xe_0_0_3_201bit in line
o687_xe_0_0_3_201bits,95,PERCENT *

So the error message shows a truncated vname 

In rrd_graph_helper.c:

   strncpy(gdp->ds_nam,gdp->rpn,DS_NAM_SIZE);
    *c=',';
    /* trying to find the vidx for that name */
    gdp->vidx = find_var(im, gdp->ds_nam);
    if (gdp->vidx<0) { *c=',';
      rrd_set_error("Not a valid vname: %s in line %s", gdp->ds_nam,
gdp->rpn);
      return 1;}

So it seems that the lookahead is getting the comma earlier than it should.
Anyone able to sort this?

regards

Bruce
