Ruby SQLite wrong argument type

Code @db = SQLite3::Database.new 'db.db' works perfectly with ruby-1.9.3-p194 and returns error with ruby-2.0.0-p353 (rvm 1.24.7):

wrong argument type nil (expected Hash) (TypeError)

I can't googling any solution.

UPD: There is no error with irb. Only with my own code:

# encoding: utf-8
require 'sqlite3'

class Model
  attr_reader :files, :last

  def initialize(dbPath = 'photo.db', tags = '', lastID = 0)
    @tags = tags
    @lastID = lastID
    $log.debug() {"Loading database: #{dbPath}..."}
    @db = SQLite3::Database.new dbPath
  end
...

It produces this trace in log:

I fixed it with replacing in executable script #!/usr/bin/ruby with #!/usr/bin/env ruby.
