Style Sheets cannot be served from S3

[koehn]

In diaspora.yml, you have the option to serve assets from an asset host. Unfortunately, if that host includes a subdirectory (as they would be in S3), the CSS will break, as they include URLs that assume they are served from the root (/assets). These should be relative URLs so they can be served from any directory.

Did you try recompiling the assets after changing the setting?
