Missing abstract in scrreprt

I have just started writing my thesis, and I noticed that the title for the abstract is not spelled out. Well, as it seems, the abstract has to be explicitly switched on with scrreprt class using the abstracton option.

\documentclass[a4paper,10pt, abstracton]{scrreprt}
