One possible source of error might be the user that your rails script is 
running as. If your normal user (as you were with the one liner test) is 
not the same as the user assigned to run the rails script then it might 
be that the rails script / user does not have permission to read the 
file or some part of the path (to be sure you could set all files and 
directories to a+r and all directories to a+x on the path to the file in 
question).

Thats all that I can think of.
