Sorry for the delay. Here, I think, is the problem: you have a custom
:set function that calls `enable-theme', and the code in `enable-theme'
calls `custom-theme-recalc-variable' to apply all variables in every
theme (to ensure that theme values are applied in the correct order).
Obviously, `custom-theme-recalc-variable' ends up calling the :set
function again, etc.
I'm not sure what's a good way to address this within Emacs itself, but
you can get around it in your own code by doing
(unless (custom-theme-enabled-p 'zen)
(enable-theme 'zen))
