4568	mc freezes for 10 seconds, after which it opens with an empty PS1 (mc, tmux).	krekhov		"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)
