Mongoid criteria problem?

gistfile1.rb

# I would expect all of the following to return the same results

# Works as expected
Article.find(:first, :conditions => { :slug => 'blah', :published => true })

# On latest beta gem errors with ArgumentError: wrong number of arguments (2 for 0..1)
# Works on latest github master commi
Article.where(:published => true).find(:first, :conditions => { :slug => 'blah' })

# On latest beta gem erros with ArgumentError: wrong number of arguments (2 for 0..1)
# Works on latest github master commi
Article.published.find(:first, :conditions => { :slug => 'blah' })

# On latest beta gem errors with ArgumentError: wrong number of arguments (1 for 0)
# Works on latest github master commi
Article.published.first(:conditions => { :slug => 'blah' })

# Works on latest github master commit
Article.published.where(:slug => 'blah').first

# Article Model

class Article
  include Mongoid::Document
  include Mongoid::Timestamps
  
  field :title
  field :slug
  field :body
  field :published, :type => Boolean, :default => false
  
  validates_presence_of :title, :body
  
  before_save :set_slug
  
  scope :published, :where => { :published => true }, :order_by => :created_at.desc
  
  def set_slug
    self.slug = title.parameterize
  end
  
  def to_param
    slug
  end
end

@kernow did you ever find the solution to this problem?

I believe this was fixed in a later version

:'(

Having the same issue on 2.4.7.

Any chance you were using the mongoid_slug gem?
