Summary:                    core dump when run against dot files from ruby 1.9
Description: 
dot segfaults on files in the ruby 1.9 source directory.  A backtrace is
below.  This may be related to the recent pixman update.

The call that produces the segfault is:
dot
/home/bwalton/opencsw/ruby19/trunk/work/solaris9-i386/build-isa-i386/ruby-1.9.2-p180/doc/capi/html/d8/d18/ruby_2ruby_8h__dep__incl.dot
-Tpng -o ~/dot.png

I'll attach that dot file for reference.

probably not pango directly... 

threads are from libgthread which is from the glib package

AFAICT from a quick read of glib's configure.ac,  it should only be using
pthread, if available, or thread as a last resort.
