#96 GTK crash stemming from JFreeChart on headless systems

[Paul N]

I have a headless system I am running StatSVN on. When I ran StatSVN, it died with a GTK error. Working with Jason over on the StatSVN mailing list, I isolated the issue to StatCVS's code that uses JFreeChart. Specifically, I isolated the crash down and found this information:

This is a consolidated set of information available over on the StatSVN thread.

---Fault output:
(.:15438): Gtk-WARNING **: cannot open display:

---It appears that this line causes the fault:
final JFreeChart chart = ChartFactory.createTimeSeriesChart(this.config.getProjectName() + ": " + title, domain, range, data, legend, false, false);
in LOCChartMaker.java

---Stack trace(line numbers not accurate for LOCChartMaker.java due to printf statements for debugging):

---Other data
Setting the property to headless immediately prior to that call does not change the crash.
