Some apps don't have a specific stable branch such as kexi or kpmcore, repo-metadata just says none for the stable branch and there's no translations in branches/stable/ they just get it from unstable but neon dev stable edition breaks as it doesn't find any translations somehow releaseme should detect this and use trunk translations
That'd need handling in the neon tooling https://github.com/blue-systems/pangea-tooling/blob/master/ci-tooling/lib/ci/vcs_source_builder.rb#L74
