Redmine

using rails 2.3.8, ruby 1.8.7, was seeing a few of the setting_multiselect calls -- specifically in /app/views/_repositories.rhtml -- rendering as encoded html. e.g. as

  <label>...

  <label>...

this was preventing setup of a new redmine installation.

wasn't obvious to me why some of the calls were encoding and others were not -- choices was coming in as a string array in all cases, but the patch above fixed all cases (because an exta CGI::unescapeHTML is innocuous).
i did not track into whether this is something about newer rails .join or check_box_tag or something else, but i thought i'd list it as a workaround for people at HEAD as a quickie workaround.
