I am afraid you need to give more information that just IOError,
calling an external program.
Please post the exact message including the input filename at the time
the program went down. If you don't print the filename, please modify
your program to do so.
A shot in the dark solution to your problem might be that you are
dynamically generating a filename and that filename probably contains
characters not allowed by the local file system OR you generate a path
that does not exist. For open() to work with the 'w' flag, the path
where the file you say should be created should exist.
Another low-probability cause is that you are trying to create files in
a non-existent directory.
