Hello Liam,

You might try to narrow the code in where the error happen. Read the
file and replace a dummy-seq-string and see what happens. Does this

"test string".replace("st st", "?")

When it works, what is bad with your file? Consider asking
comp.lang.python for a greater audience.

BTW: some time past the base64 module (base64 is a mail attachment
encoding) has a bug leading to a MemoryError when undecoding an empty
base64 string. Any free GB of ram did not help.

You can allways work arround the replace:

new = old[:start] + relace_string + old[end:]

which is ugly but perhaps makes your script running.
