I'm having the same problem. Tested it last week and from the core dump
I gathered it crashed it rrd_set_font_desc which apparently is a new
function.

Specifically, the 'font' pointer passed as 2nd param to 
strncpy(im->text_prop[prop].font, font, sizeof(text_prop[prop].font) - 1);
apparently was a null pointer which went in there unchecked.

Switched back to 1.3.0 cause I had other issues on hand at the
time. Having a mixed cairo/pango library setup I couldn't convince
myself to report the problem, cause I'd have felt obliged to further
investigate.

Maybe 1.3.2 wasn't a mere bugfix release?
