This keymap is provided by the complist module that you loaded initially, then sequentially deleted with ''bindkey -d'' returning the keymaps back to a default state. The zsh/complist is loaded automatically on first use of menuselect, which explains why ''zmodload zsh/complist'' is required for the segfault. If my guess is true, zsh should handle the menuselect keymap not existing more elegantly. But i wouldn't expect menuselect to be of much use without keybinds.
