qDebug/qWarning/etc messages should simply not translated, for few
reasons:
- with GUI-based applications, users won't simply see them unless
  launching them from a console
- debug messages (depending on kdelibs/qt version, and API used) can be
  enabled/disabled from outside the application, so they can be even
  "missed" by users
- in general, using debug messages is a poor user feedback for GUI
  applications

So yes, please remove i18n() from the aforementioned debug messages.
This is what I usually do when reviewing strings in some
application/library.

Thanks,
