Unfortunately, this is a problem for me, as well. I am using KeePass2 with its database on other devices syncing it via owncloud and KeePassX won't open the database as it's having a different structure (it only works for databases of version 1.x). And now?
Edit: Exporting to a database for KeePass 1.x did the job. But after updating to Jessie everything went fine with KeePass2. Then I moved to a RPi3 with Ubuntu Mate which works like a charm (without probs concerning KeePass 2).
