Wow, thanks for your thorough and painstaking reply. I do appreciate it.

Notes below...

Yes, my front page has a similar link.

In my front-<digest>.css, the link is to:

     background:url(/assets/ajax-loader-5ba2a014bf17ca29b030deebd5a45451.gif

... but there is no public/assets/ajax-* to be found, with or without the 
digest. So my error message in the log is:

I, [2015-05-14T21:56:13.309471 #37560]  INFO -- : Started GET 
"/assets/ajax-loader-5ba2a014bf17ca29b030deebd5a45451.gif" for 127.0.0.1 at

So it seems that in your case the "asset fingerprinting" (adding the

Yep, confirmed those.

Correct.

Yes, with a different digest of course.

- When visiting the home page, the HTML contains a line like: 
>   <link class="app-stylesheet" 
> href="/assets/front-0d5a7dfd61d432ac4d1fa6a0a7b7ce0b.css" media="screen" 
> rel="stylesheet">

Yes mine is: 

     <link class="app-stylesheet" 
href="/assets/front-9bba951313df09b74b77547b97454d00.css" media="screen" 
rel="stylesheet">

... and that file exists.

The only other curious thing, which may only indicate the way Chrome 
developer mode displays stuff, is that Chrome says that front-*.js 
requested ajax-loader, not front-*.css. That may be nothing...

Anyway, let me know if you have any thoughts. I can certainly find 
ajax-loader files, and I guess if  I jam one into images, it will be 
compiled. But I would llike to get to the root of the problem.

Thanks again very much.
