Also, could you try to pull from their git and compile that version of cairo. Second, could you try to use an older version of libgcrypt if possible. Just if you have the time.... So the error means cairo is passed an invalid matrix, hmmm. Well, anyway thanks for your debugging so far, keep it up. Cheers.
