The 'worker' MPM has not been tested; only pre-fork.  But this seems unrelated 
to this issue.  We'd love to hear about your experiences on the 'worker' MPM 
once this is resolved.

Can you give a more complete set of logs like this:
  1. set your loglevel to 'info'
  2. stop your server
  3. delete your log
  4. start your server
  5. refresh your page from your browser
  6. attach the contents of the log to this Issue
That might tell us some useful things (as well as a few things we'll need to 
ignore).  You'll want to set your loglevel back to 'warn' or something after 
that so you don't fill your disk.

Other information that would be useful:

 - any ModPagespeedDomain lines in your conf file
 - the URL you used in your browser to exhibit this behavior
 - the HTML fragment referencing stylesheets/base_7189.css

Here is the additional information: 

The configuration is as follows:
1)     ModPagespeedDomain http://staging.zoomin.co.nz
    ModPagespeedDomain http://images.zoomin.co.nz
2) http://staging.zoomin.co.nz is a proxy to an internal address 127.0.0.1:8080 
.
3) I hit "http://staging.zoomin.co.nz" to get the behaviour.
4) CSS <link href="/stylesheets/base_7189.css" media="screen" rel="Stylesheet" 
type="text/css"/>

How are you setting up the proxy to 127.0.0.1:8080.

By the way we have added new conf file directives ModPagespeedMapRewriteDomain 
and ModPagespeedMapOriginDomain so that we can do this transformation for you 
in mod-pagespeed.

This is in the SVN trunk but is not in the branch made last friday or the 
binary release we will make this week.

This is fixed via the directive ModPagespeedMapOriginDomain.  See the FAQ.
