Rails - Sep 2005 - activerecord, sqlite2 and rollback error...

I''m having some trouble with active record with sqlite2. I''m
getting a
undefined method `rollback'' for #<SQLite::Database error.
I''m not sure
what I have done wrong.

                :order => "path",

  path = if tif.path =~ /LOCAL/
           sprintf "%sLOCALSTORAGE/%s", base[:LOCAL], tif.path
         else
           sprintf "%s%s",base[:OPTICAL], tif.path
         end

  if File.exists? path
    oldsize = File.size path
    newpath = "#{image_dir}#{tif_name}"

    FileUtils.cp(path, newpath)

    newsize = File.size newpath

    if oldsize == newsize
      tif.processed = 1;
      tif.save
    end
