Summary: os.chmod failure
Initial Comment:
When running on Linux and accessing a FAT partition, os.chmod fails with
otherwise sensible partitions:
>>> os.chmod("/media/IHP-100/Test.lyx", 400)
>>> os.chmod("/media/IHP-100/Test.lyx", 600)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
OSError: [Errno 1] Operation not permitted: '/media/IHP-100/Test.lyx'
The only thing that seems to be allowed is `4'.

Note: you are *not* using octal in python, but the chmod program is using
octal:
Try prefixing 400/600 with a zero, ie: 0400 or 0600.

Well, the shell's chmod doesn't return an error.

I don't know what would happen in C, say.

Why do you think this is Python's fault? os.chmod() is only a very thin
wrapper around the OS' chmod().
