I have 200+ users and the same problem.
Not clean but I just deleted the following block at the end of app/views/issues/new.html.erb :

  <% if @issue.safe_attribute? 'watcher_user_ids' -%>
      <p id="watchers_form"><label><%= l(:label_issue_watchers) %></label>
      <span id="watchers_inputs">
        <%= watchers_checkboxes(@issue, @available_watchers) %>
      </span>
      <span class="search_for_watchers">
      <%= link_to l(:label_search_for_watchers),
                  {:controller => 'watchers', :action => 'new', :project_id => @issue.project},
                  :remote => true,
                  :method => 'get' %>
      </span>
      </p>
    <% end %>

Thanks for your answer Gurvan but deleting this code is not possible add watchers
