I am not able to change avatar of "system" user

[Roman (Roman Rizzi)]

We just fixed this. See:

Can't change system user profile picture independently of small logo

I just pushed a fix: https://github.com/discourse/discourse/commit/7ac9a4d2ecac873f80e0ebb4862a3a37f078bcd0 You can opt-out by disabling the use_site_small_logo_as_system_avatar setting.
