Redmine

Setting the target version to 5.1.8.

The patch causes an error when the watcher list contains a group.

ActionView::Template::Error (Association named 'email_address' was not found on Group; perhaps you misspelled it?):

Causes:
ActiveRecord::AssociationNotFoundError (Association named 'email_address' was not found on Group; perhaps you misspelled it?)

    12: <h3><%= l(:"label_#{watched_klass_name}_watchers") %> (<%= watched.watcher_users.size %>)</h3>

    16: <h3><%= l(:"label_#{watched_klass_name}_watchers") %></h3>

I have updated the patch to fix the error. The group now also has an 'email_address' association, which always returns nil.

Setting the target version to 6.1.0.

Committed the patch in r23722.
