Found this article
here (in German). To summarise:
* Ground personnel used incorrect baggage weights for about 80 pax. 14 kgs instead of 23 kgs (assuming 2 pieces/pax).
* Pilots needed two attempts to raise the nose for the airplane to become airborne, plane was overweight.
* Incident was not reported to the German LBA (Civil Aviation Authority) because no "operative parameters" had been exceeded.
The rest is just typical blablabla. Am just stunned about the last headword...
