Description

If you add a deploy key to a repository and delete the repo, the deploy key will persist in deploy_key table and reference a repo which does not exist anymore. The key also stays included in authorized_keys and can be result in problems if the key is used for other repositorys but in a different mode (read/write).

I believe this was fixed in #5939
Updating to 1.7.2 should fix this issue.

@jolheiser thanks, I will upgrade and report back

Fixed. But I have to clean up my database by my own.
