[horde] Problems migrating my DB to horde4

[Thomas Buehlmann]

Hello List!

I have a problem migrating my "old" horde DB to new version4 on my  
opensuse 11.4 Box.
Everything works just fine, except the kronolith-part.
I get the following error by executing

$  /usr/bin/horde-db-migrate -d kronolith up

-----------------

All the other applications worked fine.
And this same database works without a glitch in H3.

Could please anybody tell me what i do wrong?

Thanks for your help!
