Hi,
most likely due to an hiccup in the kde_projects.xml file, the generation of 
files for kde-workspace (both messages and docmessages) in 
branches/stable/l10n-kf5 could have some problem; please ignore that module in 
the stable-kf5 branch for ~24h from now, (so don't remove apparently obsolete 
files or update them) until the next regeneration (maybe nothing will change, 
but it could happen that some translations will be copied again from trunk).

Sorry for the inconvenience.

Ciao
