Dia uses language packs, which include the translations of its .desktop file. These are imported into Launchpad and then exported.

Normally, before they are imported, they are stripped from the source .desktop file, which is then shipped with no translations, which will actually be loaded from the .mo files in the language packs (see https://wiki.ubuntu.com/UbuntuDevelopment/Internationalisation#Desktop%20Entries).

However, the .desktop file is shipped with full translations, which override those in the language packs. In order for them to be stripped, the X-Ubuntu-Gettext-Domain must be added to the .desktop file.
