Hi Peter,

Sorry, I didn't have time to investigate this until now.

There has been a change in CFFI, AFAIK cl-cairo2 uses the new
interface.  My cffi version is 20080217-1, which does not appear to be
in Ubuntu, so you should do a manual install from the repository.
BTW, my version is from the latest (unstable) Debian package, so maybe
it would help to nudge the Ubuntu maintainers to package the latest version.

Please try the new version of CFFI with the original code, and tell me
if the error persists.
