Admin page 500 error


Dear all,

In the past I’ve been successfully using radiant with mod-fcgid, but now
I decided to try radiant with mongrel_cluster behing apache2

I setup a mongrel cluster following the instruction I found
My goal is to be able to deploy radiant web sites using apache
VirtualHost directive, and to access the corresponding /admin panel of
each web sites.

I’m able to setup different virtualhost as radiant “istances”, I see the
classical "Your Blog Name

a really amusing tag-line here" page, but when I try to access the
/admin panel I receive an error message.

Status: 500 Internal Server Error
Content-Type: text/html

Application error (Apache)
this error message for exceptions thrown outside of an action (like in
Dispatcher setups or broken Ruby code) in public/500.html

I though this was related to some incorrect permission in the related
public dir, but group access seems ok (mongrel user 755 mode)
-rwxr-xr-x 1 mongrel mongrel 318 2007-06-11 21:54 500.html

According to error.log the connection is correctly balanced

Any ideas ?
