Comment (by dlh):

 @seancjones: I found your patch after encountering this bug recently, and
 it works as expected.

 However, I'm not sure it's true that `init` is not fired during
 installation. I called `did_action( 'init' )` just before
 `flush_rewrite_rules()` in `wp_install()` and got back `1`.

 If I'm reading correctly, the taxonomies are registered on `init` during
 installation, but permastructs are skipped in
 `WP_Taxonomy::add_rewrite_rules()` because

 {{{
 is_admin() || '' != get_option( 'permalink_structure' ) )
 }}}

 is `false` (a permalink structure is usually set in
 `wp_install_maybe_enable_pretty_permalinks()`, though).

 Also, I think there's still a chance that third-party code will run during
 installation. For example, if `WP_DEFAULT_THEME` registers taxonomies, it
 would be subject to the same bug. Firing `init` fixes the bug, but it
 seems like it will also cause whatever is hooked to `init` to run twice,
 which callbacks might not expect.
