It will be good to have better translation strings

[Bartosz Kosiorek]

Current translation contains ENTER (new lines) at the end, and also spaces at the beginning.

You could use following pattern (taken from clock app):
 i18n.tr("Next Alarm %1").arg(get_time_to_next_alarm(activeAlarmDate - clockTime))

For plural form please use:
i18n.tr("%1 cookie per second.", "%1 cookies per second.", cookiesVar).arg(cookiesVar)
because some language have more than one plural form.
