Description
I discovered strange behavior of mc after exiting the tmux session. I checked this bug on Manjaro and Debian, package versions are listed below. The point is that mc freezes for 10 seconds when opened, then opens without PS1, only the '$' symbol is visible in the mc prompt and if return to tmux, in session 0 you can see the 'Bad file descriptor' errors (see 'b.png' screenshot).
--- Actions
-> install mc and tmux latest versions
$ sudo useradd -m -s /bin/bash tester $ sudo passwd tester $ sudo echo "[ -z \"\$TMUX\" ] && tmux" >> /home/tester/.bashrc $ su tester $ mc
mc opens well, PS1 is present.
-> exit from mc
-> exit from tmux
$ mc
or
$ mc -U
10 seconds wait, then PS1 will be empty. I expected that mc would open immediately and PS1 would be present there (see 'a.png' screenshot).
$ sudo mc
mc opens well, PS1 is present.
$ mc -u
mc opens well, PS1 is empty (that's how it should be, because '--nosubshell')
-> exit from mc
$ tmux
-> ctrl + b + s
-> select session 0 from the list
-> there will be errors (see 'b.png' screenshot)
