[kronolith] Fatal error in reminders.php

[Andrew Webber]

I love Horde!  However, I am having some trouble getting my 
reminders.php script to work at all.  When I run the script I get this 
output:

> PHP Notice:  Undefined index:  calendar in 
> /horde/kronolith/lib/Driver.php on line 171
> PHP Warning:  
> Kronolith_Driver::factory(/horde/kronolith/lib/Driver/.php): failed to

I am running the latest stable versions of horde and its applications:
> Address Book (turba)  H3 (2.0.5)
> Calendar (kronolith) H3 (2.0.6)
> File Manager (gollem) H3 (1.0.1)
> Filters (ingo) H3 (1.0.2)
> Horde (horde) 3.0.9
> Mail (imp) H3 (4.0.4)
> Notes (mnemo) H3 (2.0.3)
> Tasks (nag) H3 (2.0.4)
I am I doing something obviously wrong?  I checked the FAQ and the 
mailing list archives, but I didn't see any mention of the same errors.

Anyone have any suggestions?

Thanks!
