The problem seems to be that POTFILES.in has been outdated, so all the translatable strings up to zenity 3.26.0 have not made it to the translation template. The latest template was created on November 13, 2017, and two weeks later several files were added to POTFILES.in upstream:
https://github.com/GNOME/zenity/commit/abcc873c So there seems to be an urgent need that GNOME releases a new version of zenity. @Jeremy: Can you push for that to happen in due time, so zenity can be updated in Debian/Ubuntu in time for 18.04? ** Changed in: zenity (Ubuntu) Importance: Undecided => High ** Changed in: zenity (Ubuntu) Status: New => Triaged -- You received this bug notification because you are a member of Ubuntu Translations Coordinators, which is subscribed to Ubuntu Translations.

For example the Czech translation: Upstream: https://github.com/GNOME/zenity/blob/master/po/cs.po - last updated in December 2017. Launchpad: https://translations.launchpad.net/ubuntu/bionic/+source/zenity/+pots/zenity/cs/+details - last updated in November 2015, missing many strings when used with the current Zenity package.
