Rails - Aug 2007 - Strange Race Condition?

I have a very odd situation.

I have a method in my application controller:

  def manual_location(city, region, country)
    result = Location.user_created(params[:new_city],
params[:new_region], params[:new_country])

    case result when true then
      return Location.find(:first, :conditions => ["city = ? AND
region = ? AND country = ?", params[:new_city], params[:new_region],
params[:new_country]]).id
    when -1 then
      flash[:error] = "There was an error saving the location to the
database."
    when false then
      flash[:error] = "You didn''t provide all three values: City,
Region, and Country"
    end
    return false
  end


This is the user_created method from the Location model:

  def self.user_created(city, region, country)
    unless (city && region && country)  # Unless we have all
three it
is invalid
      return false
    end

    # Either case below it should exist by the time we finish so
return true

    check = Location.find(:first, :conditions => ["city = ? AND region
= ? AND country = ?", city, region, country])

    if check
      return true
    end

    location = Location.new(:city => city, :region => region, :country
=> country)

    if location.save
      return true
    else
      return -1
    end
  end

When I call the method from one controller it works no problem,
however when I call it from a different contoller I get NilClass
errors.

This doesn''t happen at all on the Windows box I have at work, I only
get the odd behavior on my Linux machine at home.

Does anyone have any ideas?

I realize the model method is ugly, I wrote it late at night and
haven''t gotten around to cleaning it up.
