As Mikel stated, the bug seems to be present in KDE SVN upstream. If it's been solved there, it might be a bug in importing the translations into Launchpad.
Asked for more information to Mikel (Basque Ubuntu translation coordinator):
* In which Kubuntu versions does this happen?
* In which translations does this happen?
Asked Marcos Goienetxe (Basque KDE translation coordinator):
* In which Kubuntu versions does this happen?
* In which packages in the KDE SVN was the problem detected and in which revision was this solved? (I could not find an upstream bug report).
