[Bug-plotutils] graph error message

[John Battle]

I am using the graphutils package from the ubuntu repository:
graph (GNU plotutils) 2.6

my platform is an intel i7 running ubuntu 12.04.3 LTS
Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz with 8G RAM
The kernel version is:  3.2.0-53-generic

When I execute the following comand:
graph -T X < data.txt
using a data file containing: 
-2 0 0 2 2 5 4 2 6 0 8 -1

The graph appears properly but when I close the graph window, I get the error message:XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"

      after 324 requests (324 known processed) with 0 events remaining.
