Nice! The next step is to run the 'lrelease' command on mixxx_de.ts
lrelease res/translations/mixxx_de.ts
This will produce a mixxx_de.qm which is the release version of the translation. Now you need Mixxx to load the .qm when it boots and activate it. I just updated the trunk to do this, so if you update to trunk, it should load mixxx_XX.qm where XX is your current locale.
