Bug#804769: Some files are not installed in any binary

[Sebastien Bacher]

Package: gnome-builder
Version: 3.18.1-1

The build log [1] has dh_install --list-missing listing quite some files
(libide documentation and .pc mostly), it would be nice to use
--fail-missing and make sure those are installed

The same sources fails to build synced to Ubuntu as well
https://launchpadlibrarian.net/225802046/buildlog_ubuntu-xenial-i386.gnome-builder_3.18.1-1_BUILDING.txt.gz

"dh_install --list-missing
dh_install: gnome-builder missing files
(usr/lib/*/gnome-builder/plugins/*/*.py), aborting
debian/rules:37: recipe for target 'override_dh_install' failed"

Unsure what's the issue there but it could be due to different python
versions...
