Why would you expect it to be in local_mbox?  local_mbox is a copy of
the old, unconverted local files from before the initial conversion.
It's not used for anything.

After you created the folder within Evolution under local, does the
directory ~/.local/share/evolution/mail/local/.fred exist?  What are its
permissions and ownership?  What are the permissions on the directory
~/.local/share/evolution/mail/local ?  What is the output of the
command 

  ls -la ~/.local/share/evolution/mail/local/

What sort of filesystem is your home directory on?

That doesn't look like a valid path, it should end in mail/local/.mackay

The bottom line is that all the things you are talking about work fine
for everyone else.  One possibility is that you have corrupted binaries
somewhere - you can test this by creating a new Linux account and
setting up evolution on that - you don't need to connect it to a server
or download any mail or convert anything.  You should be able to do the
operations you are talking about (like create folders etc.) without any
problems on the pristine evolution.  If you can't, then there is
something seriously borked with your system.
