Thanks for the fix. I've been using zsh as my default shell for more than 2 decades and intend on keeping it that way ;-)

Anyway, I decided to change the detection logic without invoking which command. (I also noticed gnu-which also lacks -s option and higher priority than debianutils which.) I just ploaded. FYI: Although zsh works like dash/bash in most cases, it is problematic to set it as so-called "default shell" in /etc/passwd. This is not the first time breaking im-config by zsh. If you want to avoid breaking system provided code, set default loginshell in /etc/passwd to bash. You can set up different shell for your GUI terminal from the profile menu. For ssh and linux virtual console, you can "exec zsh" conditionally at the end of your ~/.profile or similar.
