Follow-Up: Debugging the request by adding Horde::debug($request, 
$filename); to rampage.php I found that the request is faulty:

2014-12-11T09:35:19+01:00 DEBUG: Variable information:
object(Horde_Controller_Request_Http)#133 (2) {
   ["_path":protected]=>
   string(18) "/horde/rampage.php"
   ["_headers":protected]=>
   NULL
}

Backtrace:
1. Horde::debug() /var/www/virtual/htjn/html/horde/rampage.php:58

Of course the request can't be correctly mapped to the appropriate 
controller...
On a working installation the request is like this:

2014-12-11T00:32:42-08:00 DEBUG: Variable information:
object(Horde_Controller_Request_Http)#159 (2) {
   ["_path":protected]=>
   string(13) "/trean/b/save"
   ["_headers":protected]=>
   NULL
}

Backtrace:
1. Horde::debug() /opt/horde/rampage.php:59

Any ideas as to what may cause this?
