Incorrect translations in settings for en_GB

[Sparhawk]

In backintime (for kde), some of the settings are in the wrong language. I'm using en_GB, and I see

Bewaar kopie van bestanden vóór herstel
Start 'ionice' als een cron job (standaard: aan)

They seem to be both related to these translations.

I can confirm that en_GB should just be the same as en in these cases.
