I think i2pd itself is (was?) unstable. In the past I had it segfaulted every after a while on other distro (not Debian-based) too. But on Debian I have switched to their upstream binary since I experienced those bugs.

I don't need all the things to be the latest. I would like to but I don't want spend up to a night unbreaking things in exchange for that (which I had experienced several times). I may only need the latest packages for a selected few. It is rather a personal taste however.
