Bitcoin Core levelDB corruption after acces from other tool.

Hi guys,some strange happend which I currently don't understand. I use the common libleveldb-dev package from Ubuntu to access the bitcoin core chainstate database from an own implementation. I haven't changed anything, I just opened the database to see all is fine, and yup, my tool says all is fine.Now, if I want to start bitcoind again, it says: LevelDB read failure: Corruption: corrupted compressed block contentsWTF? Is there something I don't know about leveldb, or are their special implementations by the Bitcoin developers. I'm absolutly confused.Thank you guys in advance. via /r/Bitcoin http://bit.ly/1TDpD8x
