Comment 10 for bug 1465753

The problem appears to be with the Cairo library. It doesn't like large numbers in the pattern transformation matrix.

I've checked code into both 0.92.x and trunk that translates the pattern by multiples of width and height so that the translation part of the Cairo transformation matrix is smaller. This isn't a complete fix as large numbers in the scaling/rotating/skewing part could still cause problems.

Please verify that the code functions properly.
