Steps to reproduce:
- Startup latest master. Ensure Chat portlet module exists and is running too (you should see chat bottom bar when logged).
- Go to Documents and Media.
- Click on "+" link in bottom right area.
Expected behavior: menu for adding DM elements should show up.
Actual behavior: menu doesn't show, so it's impossible to add new elements.
Workaround Remove *.chat.web.jar module from osgi/modules folder.
