[ingo] Fatal Error: Call to a member function on a non-object in Ingo.php on line 129

Hi,

when I want to activate the script I'm getting

Fatal error: Call to a member function on a non-object in  
/var/www/html/horde/ingo/lib/Ingo.php on line 129

I'm using CVS version and procmail as the backend.

Thanks.

Bye

Volker
