Python editor: Value cannot be null. Parameter name: replaceWith

[DanielSeara]

At any time a .py file is saved, debugged etc. the message appears and the file cannot be edited anymore, unless you close and reopen the file. In my case, I'm using the local file system Do NOT mark it as closed since there is no work on it.
