Hi, Tim.

I've just checked and found that exactly the same problem exists for 
"zsh". On a command-line login shell, these startup files are sourced:

   /etc/zsh/zshenv
   /etc/zsh/zprofile
   /etc/zsh/zshrc
   /etc/zsh/zlogin

Invoking an interactive sub-shell from the login shell only sources:

   /etc/zsh/zshenv
   /etc/zsh/zshrc

Setting Gnome Terminal to run "zsh" as a login shell sources:

   /etc/zsh/zshenv
   /etc/zsh/zprofile
   /etc/zsh/zshrc
   /etc/zsh/zlogin

By default Gnome Terminal runs "zsh" as an interactive shell and only 
sources:

   /etc/zsh/zshenv
   /etc/zsh/zshrc

HTH,

   Tony.
