So basically the claim is that because of this vulnerability it is possible to complete a 51% attack.
Is that or is that not also a possibility with pure PoS coins?
I'm not seeing how the security status of blackcoin is any different than the security status of mintcoin, as both are supposedly vulnerable to this attack. Which from what i gather is quite expensive to launch successfully and therefore highly unlikely in the first place.

Okay, for your understanding:
1) All coins ever created are suspectable to 51% attacks.
2) Mintcoin is PoW/PoS hybrid
3) We have succesfully tested a hypothesis that prevents PoS blocks from being accepted. - This means that MintCoin was PoW-only for one full hour.
4) Due to the low rewards on the Mintcoin PoW chain the hashrate is low. This means that during that time that MintCoin is PoW-only it is very easy to perform a 51% attack.
