    Description

      MaxScale crashes on startup with the following backtrace:

      2016-04-28 11:16:58   error  : Commit ID: source-build System name: Linux Release string: NAME=Gentoo Embedded library version: (null)

      I've tracked the problem down to the following commit: https://github.com/mariadb-corporation/MaxScale/commit/7f18c579a4615eb505e8fee89aacd213f704223d

      It looks like in my setup, server->server->server_string is NULL at that point, causing the crash in the strstr call.

      Please let me know if I can do anything further with regards to testing or providing you with more information.
