Ok, I went to go file a bug and I found the original bug report ( 
https://bugzilla.mozilla.org/show_bug.cgi?id=2875 ).  It is from 1998!

If it hasn't gotten fixed by now, it's not likely to.  But I think the 
main problem is that there is no clear resolution on how to fix it.  
Polipo returns a 504, and other proxies return different codes.  Is it 
impossible for a proxy to return a "host not found" DNS response instead 
of or in addition to an HTTP response?

Also: squid allows for a workaround in that you can configure the error 
page.  Thus, a custom error page can give a link to the "I'm Feeling 
Lucky" or whatever.  Polipo doesn't allow for this, does it?

Thanks!
Daniel
