Description of problem:

It's more visible in Chrome, which displays a broken image icon, but it's evidently a server-side issue

When loading some panes, the spinner image is missing.

Infuriatingly, I am not 100% sure of these steps actually.  It seems kind of occasional.  It /may/ be a particular navigation path that is causing it. Specifically, it may be occurring when navigating from, say, Locker to Dev and doing a package list.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1.  Assure you've created a non-locker environment ("Dev")
2.  Use a RH manifest  and sync rh content
3.  Promote content to Dev environment
3.  Content management > Promotions > Locker
4.  In the left pane, Red Hat Enterprise Linux Server > Packages
5.  Chose "Dev" from the environment at the top.
6.  In the left pane, Red Hat Enterprise Linux Server > Packages; wait for page to load

  
Actual results:
No spinner (sometimes!).  In chrome, a broken image is rendered.

Expected results:
Spinner

Additional info:

I have not yet been able to discern why SOMETIMES it loads and sometimes it does not.  But I have discovered that
* Sometimes it tries to load the correct URI, /katello/images/spinner.gif
* Sometimes (when exhibiting broken behavior) it tries to load an apparently incorrect/missing URI, /katello/promotions/images/spinner.gif
