Fossil [1] has always been my go-to DVCS for ages. Not only can I host it myself. I can also run it when completely offline. It offers Bug Reporting, a Wiki and both a web interface and CLI.

Created by Richard Hipp, creator of SQLIte, it's open source and free, has zero dependencies and works across all operating systems.

And even if you don't want to host it yourself, there's always chiselapp.com [2]
