I have sorted it out with SAS now. They had my Krisflyer account on the original booking but somehow exchanged it for my Eurobonus. They have offered me to fix the mess later if I keep the boarding cards.

In the end it will all be good though: I get twice the points (200% points in C) on Eurobonus and this trip alone will make me * Gold. I will also get about 20-22 sectors for PPS with 11 months to get the last sectors. Getting Krisflyger PPS will give me Krisflyer Gold also - so in the end I will have * Gold on both SK and SQ.
