It seems that next is nil here:

gitea/routers/web/base.go

Line 65 in 08507e2

next.ServeHTTP(w, req)

Found the root cause - I had a trailing / after the port in my ProxyPass directive in Apache config, and because of this all requests began with //. It would be nice if the server didn't panic in that case.

To reproduce the panic:

curl -I "http://yourhost/gitea//avatars/a"
