CSS file not loaded. Recognition failed ?!

Rails
1

Hello,
I’m having a very strange issue. I’m launching the rails app with
webbrick, but the browser doesn’t always load the css file.
I’m using <%= stylesheet_link_tag ‘cascada’, :media => ‘all’ %> to link
the file, where cascada.css is the stylesheet of course. Pointing the
browser directly to ‘http://localhost:3000/stylesheets/cascada.css’ may
sometimes work, and some times does not and i really can’t figure it
out. Refreshing the page renders the page well again but only in
Konqueror (though i have to do this every time, on every page). Gecko
based browsers don’t render the css after refreshing the page - period.
On further inspection the css they load has this instead (yes, this is a
css file, not html):

Action Controller: Exception caught body { background-color: #fff; color: #333; } 
body, p, ol, ul, td {
  font-family: verdana, arial, helvetica, sans-serif;
  font-size:   13px;
  line-height: 18px;
}

pre {
  background-color: #eee;
  padding: 10px;
  font-size: 11px;
}

a { color: #000; }
a:visited { color: #666; }
a:hover { color: #fff; background-color:#000; }
