When a user presses the secondary mouse button on e.g. a directory named "a" that has 372 KiB, and chooses "Calculate occupied space" -> it's seen:        
    Total occupied space: 372 KiB (381 026 Kbytes)(I18N_PLURAL_ARGUMENT_MISSING) in 1 directory and 5 files
    
Note: This comes from the line
    msg = fileName + i18n("Total occupied space: %1", KIO::convertSize(totalSize));
in
    krusader/krusader/Panel/krcalcspacedialog.cpp


Reproducible: Always
