And this problematic code wasn't in the source you posted :-)

For a cleaner solution, you could use the same block form that you were 
using for the zip files:

File.open("kml/#{@file_names[file_index]}","w") do |file|
  file.write(@kml_file_data.to_xml)
end

This is better because the file will *always* be closed, even if an 
exception is raised in the block.
