Dear all,
when I C-c C-c in:

#+BEGIN_SRC sh
gnome-terminal
#+END_SRC

a gnome-terminal window appears, but  Emacs hangs until I close it.
In the *Messages* I get:

executing Sh code block...
Wrote /tmp/babel-2307H-J/ob-input-2307i3c
(....here Emacs hangs... then I close gnome-terminal)
Error reading results: (beginning-of-buffer)
Code block produced no output.

If I use emacs -Q ( evaluating just (org-babel-do-load-languages
'org-babel-load-languages '((sh . t))) ) this doesn't happen.

Do you have any idea of what could be triggering such behavior?

Thanks,

Giacomo
