I agree. I suggest doing a build with a debug python interpreter, then
you get a very helpful error message:

Bug#828929: cairocffi: FTBFS with gcc-6 and glibc 2.23

[Jean-Christophe Jaskula]

Hi Daniel,

I believe this package fails to build randomly because of a test times out 
depending on the charge on the CPU. The FTBFS already occurs on 
testing/unstable and in my pbuilder sometimes. I don’t think it has anything
to do with gcc/glibc. I will poke the upstream to see how modify this test.

Thanks,
JC
