virtualenv is a tool for creating isolated virtual python environments. Prior to 21.14.7, the bash activate script escapes the environment name for only one of the two passes bash makes over PS1, so a backslash in the name undoes the escaping and a name containing $(...) runs as commands in the user's shell each time bash draws the prompt. This issue is fixed in version 21.14.7.
