Missing locale in latest image?

[ThimoNeubauer]

I noticed that our daily calls of /opt/teamcity/bin/maintainDB.sh started showing messages about missing locales on stderr. The effect is straightforward to reproduce:

[tnr1@eu-dar-tnr1-ds8 ~]$ docker run -it --rm jetbrains/teamcity-server /opt/teamcity/bin/maintainDB.sh

You can see that perl is missing the "en_US.UTF-8" locale.

10 days ago a new image was pushed. I tried the previous image which doesn't show the warning on stderr:
