Comment:

 Addition: it produces even more weird errors in the admin_tools dashboard,
 when viewing a specific app:

 {{{
 Caught AttributeError while rendering: 'NoneType' object has no attribute
 '_meta'
 }}}

 which happens somewhere in the `contenttypes` framework:

 {{{
 File "/usr/lib/python2.6/site-
 packages/admin_tools/dashboard/templatetags/admin_tools_dashboard_tags.py"
 in admin_tools_render_dashboard_css
   90. dashboard = get_dashboard(context, location)
 File "/usr/lib/python2.6/site-packages/admin_tools/dashboard/utils.py" in
 get_dashboard
   21. return get_app_index_dashboard(context)

   71. return getattr(mod, inst)(app_title, model_list)

 When an abstract model is registered with `admin.site.register()` it
 produces the following error later on:

 {{{
 type object '...' has no attribute '_default_manager'
 }}}

 This error does not make much sense unless you're already have more
 intimate knowledge of the framework. [[br]]
 To ease the learning curve of new developers, I think it would make sense
 to check whether the model is abstract or not.
