Guys, thanks a lot for helping!

Indeed the main reason were lost translations in the po file. After re-creating
the po file and merging the old translations they now appear translated except
a few ones:

- all date/time values in column activity (yesterday, month ago, day, ago...)

- the first item in selection boxes which is '- no selection -' (encountered
  also when using the jinja2 templates - which I like very much btw.)

The latter item is translated and in the po file:

#: ../html/issue.item.html:122 ../html/issue.item.html:197
#: ../html/issue.item.html:220
msgid "- no selection -"
msgstr "- nichts ausgewählt -"

Cheers,
Mathias
