Hi Miguel,
Not sure if this has been fixed upstream (in core Cairo) but according to
comments on this bug report (
https://bugs.freedesktop.org//show_bug.cgi?id=19655), it looks fixed in the
latest version. I compiled Cairo from source and replaced the libcairo but
got in to more problems (most likely I was doing something wrong). I cannot
confirm that this has been fixed upstream. Nevertheless, it would be nice if
the latest version of Mono comes with the latest version of Cairo.

Will file the bug report for sure.
