Reporting in English although it's for German locale as I think the problem might be a general problem. So when you think it is not a problem of the translation please reassign to appropriate product - I guess plasma.

I had a look at some KRunners today and I noticed that the KRunner keyword "power profile" is translated to one word "Energieprofil" in German. That's in general OK and the keyword is marked with "Note this is a KRunner keyword".

Now I had a look at the code and noticed that there is functionality relying on the fact that the keyword consists of two words (kdebase/workspace/plasma/runners/powerdevil/PowerDevilRunner.cpp line 186 following):
if (term.startsWith(i18nc( "Note this is a KRunner keyword", "power profile"))) {
foreach( const QString &profile, m_availableProfiles ) {
    if ( term.split( ' ' ).count() == 3 ) {
        if ( !profile.startsWith( term.split( ' ' ).at( 2 ) ) ) {
            continue;
        }
    }

So as soon as you start to enter another word it will only list those matching. E.g. "power profile Perfor..." will only list the Performance entry. If I want to do the same in German with "Energieprofil Perf..." the non-matching entries are not hidden as the first check for three parts fail. If I add another word the match works again. E.g: "Energieprofil foo Perf..."

This is rather annoying as the translation removes functionality. Of course the translators cannot know that there is functionality checking for the number of words. Btw. if the translation would be more words the result would be worse.
