The KDB (V1.x) file export is corrupted in V2.20. Worked correctly in V2.19. Consequence: KeePassMobile V0.9.1 (http://www.keepassmobile.com/) rejects database with message: "kdb file invalid: wrong version". Is this a bug in Keepass V2.20 or in KeePassMobile V0.9.1?
HowTo: create a new database with Keepass V2.20 (only examples in there) and export in KeePass KDB (1.x) format. KeePassMobile V0.9.1 open database fails now.
