Bar/Pie Chart issue

I’ve not been able to find a clue in the lists and was wondering if
someone could point me in the right direction. Pie and Bar charts aren’t
working in my 3.6.4 install. Using FreeBSD with Apache2 and ModPerl2.
Charting works fine in Webalizer (generates png graphs), so I’m assuming
it’s not an issue with GD. Where do I begin? Here’s what the properties
of the “red x” show (I’m manually adding the line break of course):

Chart?Order=ASC&ChartStyle=bar&Query=Queue%20%3D%20’Support’%20AND%20(Status%20%3D%20’open’%20OR%20Status%20%3D%20’new’%20OR%20Status%20%3D%20’stalled’)

&Rows=50&SecondaryGroupBy=&OrderBy=id&PrimaryGroupBy=Status&Format=

and here is the referenced URL:

http://support.southwood.org/rt/Search/Chart?Order=ASC&ChartStyle=bar&Query=Queue%20%3D%20’Support’%20AND%20(Status%20%3D%20’open’%20OR%20Status%20%3D%20’new’%20OR%20Status%20%3D%20’stalled’)

&Rows=50&SecondaryGroupBy=&OrderBy=id&PrimaryGroupBy=Status&Format=

I enter the URL in lynx and get an “unexpected network read error”

The apache access-log shows a 200 code.

I am seeing a message in /var/log/message that says httpd is exiting on
signal 6

I get a red x and a table with data below.

What next?

Thanks for any help you can provide.
