So it appears line 1488 of cairo.c is making a call to cairo with something essential undefined with -dev pngcairo. -dev xcairo did not have any such valgrind errors. Also, revision 10861 of cairo.c generated no valgrind errors (or segfaults) with -dev pngcairo and produced a good looking png result. Hope these multiple clues help you to get quickly to the bottom of this segfault. Alan, Thank you for the detailed report.
