Redmine

If an admin choses no text formatting ('none') instead of the default 'textile' then there are no entries in @@formatters in lib/redmine/wiki_formatting.rb. Therefor when formatter_for(name) is called name is blank and to_sym raises an error as it can't create a symbol of an empty string.

A sample backtrace is:
