I'm testing the apipie extensions that allow a plugin to add it's docs to the /apidoc pages. Currently if I install foreman-bootdisk (v5.0, see https://github.com/theforeman/foreman-packaging/pull/568) then I can go to /apidoc/v2.en_GB.html and I correctly see:

Disks
Resource     Description
GET /bootdisk/api                     Boot disks
GET /bootdisk/api/generic            Download generic image
GET /bootdisk/api/hosts/:host_id     Download host image

If, however, I vist the default page (/apidoc/v2.html) which should also use English, I instead see:

Disks
Resource     Description
GET /bootdisk/api                   Startdiskar
GET /bootdisk/api/generic           Ladda ner generisk avbildning
GET /bootdisk/api/hosts/:host_id     Ladda ner värd avbildning

This is possibly due to the locale not being initialized correctly for the default pages.
