For questions about the password and information manager KeePassX. There is a separate [keepass] tag for KeePass Password Safe. Use only the tag specific to your product.
KeePassX is a fork of KeePass.
From Wikipedia: KeePassX started as a Linux port of KeePass, which was at that time an open source but Windows-only password manager. Both are now cross platform, with KeePassX using Qt libraries and recent versions of KeePass using .NET / Mono.
Because KeePassX is now substantively different from KeePass, issues are likely to be product specific, so only the relevant product tag should be used.
