The attached patch allowed me to migrate my strip database to KeePassX. Sorry, it's against version 1.0.1, I didn't notice I wasn't up to date until after I'd finished. I don't know if it makes sense to include this in your distribution, but here it is in case anyone else is looking for such a tool.
Applied to 1.7, then merged up to the latest.
Checked in as 1.11, no release unless I hear a cry from the many fans of strip!
