I think I tracked it down, thanks Mark.

Here's where the error occurs:

set fileText to read thisFile
tell application "TextCommands" to set fileText to convert linebreaks  
fileText to Unix format

   Because the file is so large, the "fileText" variable is empty, and  
when the script is ready to write the converted text back to the file  
it generates a trapped error that leaves the original file untouched.

So I think what I really need to is a way to convert line breaks on a  
huge file without having to read it into memory.
