Redmine

I'm getting a strange error on a few of the issues from various projects and I'm having some trouble pinning down the root cause.

This is a db that was migrated from v.6.3 -> v.6.4 -> v.7.3 using the documented rake commands for updating/migrating the db.

Aside from these few issues all other features are working great and the vast majority of issues have 0 problems whatsoever.

For example, when I browse to http://example.redmine.hostname/issues/show/7 I receive the following error, and below the error the an application trace log:

NoMethodError in Issues#show

Showing issues/_history.rhtml where line #5 raised:

undefined method `name' for nil:NilClass

Extracted source (around line #5):

2: <div id="change-<%= journal.id >" class="journal">
3: <h4><div style="float:right;"><= link_to "##{journal.indice}", :anchor => "note-#{journal.indice}" ></div>
4: <= content_tag('a', '', :name => "note-#{journal.indice}")%>
5: <%= format_time(journal.created_on) > - <= journal.user.name ></h4>
6: <ul>
7: < for detail in journal.details >
8: <li><= show_detail(detail) %></li>

Trace of template inclusion: /issues/show.rhtml

RAILS_ROOT: /var/www/redmine-0.7

I've attached a txt file with the full txt of the trace for you to see, as well as the "Request" and "Response" sections of the above error page..

Any help would be much appreciated.

This install is using the latest Ruby/Rails/Gem updates on a CentOS 5.1 installation. Redmine v .7.3

Thanks!
