Comment 4 for bug 1696418

@Sebastien: One theory about what might have caused this is that the latest full langpack update for trusty happened at a point of time (2016-07-20) when gnome-user-docs had been moved to universe, and hence was ignored by the langpack builder.

The easiest way (workaround) to fix it is probably to rebuild gnome-user-docs without translation stripping. (Would add approximately 8 MB to the ISO.)

The not-so-easy way is a full langpack update for trusty (without testing as a requirement to move the packages to -updates), while making sure somehow that gnome-help isn't ignored. Might need to be preceded by a no-change rebuild of gnome-user-docs.
