[cairo] cairo 1.12 crashes X server

[cu]

Will follow your suggestions, thanks!

It would be great if this could be also looked at on Cairo side. The
crash occurs on a number of common distributions which means that our
application cannot be used on these. Telling users to "upgrade" is, as
you are probably aware, not a popular suggestion (they'll just dump our
application instead).
