[kronolith] 'mail' not configured

[Bjørn Ove Grøtan]

Running the latest stable-rel. of horde,imp,turba,mnemo,nag and
kronolith (not cvs).

Everything works fine, I can read and send mail, addressbooks works
flawlessly - and the same with mnemo and nag. When I try to use
kronolith (configured as described in docs/INSTALL) I get the following
error-message:
<---------------------------------------------------------------------->
A fatal error has occurred:

'mail' is not configured in the Horde Registry.

[line 753 of
/usr/local/webmail/shtdocs/horde/lib/
Registry.php]

Details have been logged for the administrator.
<---------------------------------------------------------------------->

>From $webroot/horde/config/registry.php =>
/* mail: Handler for sending mail. */
$this->registry['mail']['compose'] = 'imp';
$this->registry['mail']['composePopup'] = 'imp'; 

What am I missing here?

I've earlier used the CVS HEAD of all applications mentioned above
working without any problems, but this setup is for my
production-installation - and I'd prefer to use stable releases for
that.
