I'm having this issue with the latest version 

90.90.160.10 - - [12/Feb/2011:05:29:06 -0500] "GET 
/php5bin/php/wp-content/themes/onecol/images/home/201007-banner1.png HTTP/1.1" 
500 - "-" "Serf/0.3.1 mod_pagespeed/0.9.15.3-404"

The problem seems to be related to mod_pagespeed with php_fcgi as it tries to 
query "/php5bin/php/" + the actual path.

Examples: http://www.conexcol.net.co and http://www.colfutbol.org

I just took a look at http://www.conexcol.net.co and I found the img link 
"wp-content/....-banner1.png" but I don't see any reference in the HTML page to 
"/php5bin/php/".

I'm trying to think of why mod_pagespeed would think that the page was based 
there.  How does /php5bin/php/ relate to this site?  I'm afraid I'm not yet 
very familiar with php_fcgi or PHP at all, for that matter.  But the critical 
question here is whether php_fcgi or some other module (e.g. mod_rewrite) does 
some kind of redirect or rewriting of the URL internally that makes 
mod_pagespeed think that the base URL of the page has "/php5bin/php/" in it.

Relative image links generated errors - Google Code
to check on my page http://mulatahosting.com/ do not see this error occurs, 
that's good.
