See below.  I've not started investigating at all.  The Julia REPL
buffer does get started so it's not an issue with Julia itself.

The backtrace below is the result of typing C-c C-c on this src block:

#+name: exampleusingfresa
#+begin_src julia
  using Fresa
#+end_src

with these header settings:

:PROPERTIES:
:header-args:julia: :tangle no :exports code :noweb yes :session
:END:

Thank you,
eric
