[horde] Oci8 error after uptade

[Ico Izquierdo]

Hi all,

I just updated all packages to Horde Groupware Webmail Edition 5.2.14.
Data base backend is Oracle.
The installation has only active imp, turba, ingo and kronolith 
applications, and with the last one there is a problem.
When I click on Calendar (Agenda in Spanish) the application shows a red 
pop-up with an Exception (and side menu shows "Loading..." with no action).
Error message:

    exception 'Horde_Db_Exception' with message 'QUERY FAILED:
    ORA-01400: no se puede realizar una inserción NULL en
    ("HORDEN"."RAMPAGE_TYPES"."TYPE_NAME") at offset 46 INSERT INTO
    rampage_types (type_name) VALUES ('')' in

Few minutes later, when I try another time the same action, it works ok.
Could you tell me what is happening?

Thank you very much.
