Recent releases of pango 1.36 use functions that are only provided by fontconfig 2.12 when compiled against sufficiently-new versions of fontconfig. Since we depend on both pango and fontconfig, and pango depends on fontconfig, we must either add pango to our jhbuild moduleset or else remove fontconfig (which would make it hard to keep tests working -> we should add pango).

EWS doesn't provide anywhere near enough output to diagnose the problem, due to bug #145697
Oh, pango is just too old.
FYI: Debian 8 jessie (that is the distro of the bots and EWS machines) has pango=1.36.8

No, it's broken and it's hard to see why; let's wait for bug #145697.
I tried to manually build it on ltilve-gtk-ews and it built just fine. But I started from a clean build, so maybe is the incremental build the one that breaks?
Comment on attachment 256449 [details] Patch OK, Carlos Lopez and I both manually did clean builds on ltilve's EWS and they succeeded, so let's proceed with this.
