[horde] Trouble updating/database error

[steffo76 at gmx.de]

Hello everyone,

I updated from hgwe 5.1.6 to 5.2.1 and receive the following error while trying to update the database:

QUERY FAILED: Duplicate entry 'test' for key 2 INSERT INTO `rampage_users` (user_name) VALUES ('test')

I have no idea to resolve this, I tried converting the owner_id in turba_objects to lowercase since this seemed to have caused problems in other installations

UPDATE turba_objects SET owner_id=LOWER(owner_id);

but that didn't change anything.

Any ideas ?

Thanks,
Stephan
