Presumably you're also new to mailing lists.

At an absolute minimum when you describe an error, PASTE the error 
message, complete with traceback, into your message.  As it stands, I'm 
left wondering which key on your keyboard can possibly "not exist."  
Perhaps it's a non-ASCII code, and you're getting some encoding error.  
That's a common discrepancy between running from a terminal and running 
from some GUI.

Even better is to specify the version of Python this program is 
presumably written in, and what Linux distro. Then you say it's a GUI 
program, so you should specify which GUI library you're using.

Now if I do a bunch of guessing, I might come up with the likelihood 
that your "Nautilus" is supplying a different current directory than the 
one the script is located in.  You can find that out by looking at:

But of course how you print that depends on what GUI package you're running.
