Sorry for the long delay. Rebuilding cairo for CentOS never worked, even after
a week of trying. So, instead I installed everything on an up-to-date debian
system and confirmed I could reproduce the bug there. NOW if you need debugging
symbols or valgrind output, I can easily oblige.

Here is a trace of the crash with full backtrace:
