Compilation error in file lib/scout_apm/logger.ex

[cpursley]

I'm getting the following strange issue when compiling my Pheonix app:

==> scout_apm
Compiling 55 files (.ex)

== Compilation error in file lib/scout_apm/logger.ex ==
** (FunctionClauseError) no function clause matching in Keyword.fetch/2

    The following arguments were given to Keyword.fetch/2:

        # 1
        {:metadata, [line: 46], nil}

        # 2
        :application

    Attempted function clauses (showing 1 out of 1):

        def fetch(+keywords+, +key+) when -is_list(keywords)- and +is_atom(key)+

Closing. This was caused by a bug in elixir 1.7.3.
