  undefined method `logged?' for nil:NilClass

Using 3c2ef2757165e23b65fd from
https://github.com/edavis10/squeejee_theme/tree/chiliproject.org

The "dd" the removed assert_tag part was supposed to find should never show up on the page in the first place (it's in a journal, not in the issue itself).

acts_as_journalized called changes as per ActiveRecord::Dirty 
(see http://ar.rubyonrails.org/classes/ActiveRecord/Dirty.html#M000291), 
the journalized model Changeset :has_many changes though, which 
made the call return a list of associated objects instead of the 
intended list of changed attributes. Replaced changes with the code
from AR::Dirty to work around that.

Iconv on jRuby does not accept an empty string as "from" encoding.
Use the default behavior from the controller instead to leave it
unspecified and thuse use UTF-8.
