virtualenv-init break mc (Midnight Commander) subshell

When this plugin is running, the midnight commander shell does not work when you press CTRL+O.

Steps needed to repeat the problem:

Create file .bash_test_rc

export PYENV_ROOT="$HOME/.pyenv" command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH" eval "$(pyenv init -)" eval "$(pyenv virtualenv-init -)"
Run bash --rcfile ~/.bash_test_rc --verbose
Run mc
Press CTRL+O
The bash shell should appear, but unfortunately it does not appear.
