After updating to 1.8, launching a session using source-file is giving trouble.
When I start tmux, a single bash window is displayed. I then do
and the session contents are displayed.
With v1.8, when I source the session once, nothing happens, and if I run the source-file command again, the session does come into view, but the following message is displayed:
/home/user/.tmux/default_session:3: duplicate session: def
After that everything is working fine.
Here is my .tmux.conf: https://pastee.org/35wdx
and the session file: https://pastee.org/vqsdg
