You cannot open a non-existing file, meaning that you cannot use the
File -> Open dialog for it. There is now a "FileMustExist" or similar
flag. I remember it fixed some bug but don't remember which one.
IMO it is logical because you can by definition only open existing
files. If a file does not exist, you must create it instead.
The right fix could be to ask if a newly created file should be added
to project which means useless questions for most people.
Or, maybe the best way is to create a file somewhere else (editor,
file manager, cmd line etc), then open it. Even an empty file can be
opened.
