"internal Error" when trying to edit a newly created repo.

[jamasi]

I created a new repository and then clicked the edit link and then I got this Internal Error:
From production.log:

ActionView::Template::Error (undefined method `empty?' for nil:NilClass):
149: 
150:       <p>
151:         <%= label_tag  "", l(:label_repository_default_branch) %>
152:         <% if [email protected]_record? && [email protected]? %>
153:           <%= select_tag "extra[default_branch]", options_for_select(@repository.branches.collect{ |b| [b.to_s, b.to_s] }, :selected => @repository.branches.find{ |b| b.is_default}.to_s) %>
154:         <% else %>
155:           <span class="label label-info"><%= @repository.extra[:default_branch] %></span>

app/helpers/application_helper.rb:1056:in `labelled_form_for'

The relevant part from git_hosting.log:

Can you do a git pull from the plugin directory and retry?

[jamasi]

The internal error is gone now, but the repo is not initialised with any readme file, but that looks like another issue.
