Need help with translating statusbar

I need help translating the string {n} {files} found in {m:.{prec}f} {seconds}. The problematic words are {files} and {seconds}. I looked at translations in other languages and found two approaches:

1. If they are kept in english they remain in english (tested with LANG=pt_BR.UTF-8 catfish)
2. If they are translated, the statusbar doesn't appear and I get an error in the terminal (LANG=nl_NL.UTF-8 catfish)

Error message
