Ah, knowing it was from prefs only was what I needed. Looks like this bug that was already fixed in Git for the next bug fix release: https://github.com/horde/horde/commit/a36f1883af3ef5c35491afd706ac1ecb178d4d3c

A: grep -iR Horde_Hooks * shows no other occurance of the horde_hooks class other than in the file already mentioned. A debugging of the file /usr/share/php/Horde/Registry.php on line 1836 shows the load of these hooks (app => conf_file): horde => hooks.php imp => hooks.php ingo => hooks.php nag => hooks.php kronolith => hooks.php turba => attributes.php turba => backends.php turba => hooks.php mnemo => hooks.php trean => hooks.php passwd => hooks.php => hooks.php the last entry does not carry an app name, which might cause the issue. This entry occurs only in the preferences area, where I encounter the problem. In other areas (e.g. Ingo), the debug outputs the loading of: horde => hooks.php ingo => hooks.php imp => hooks.php nag => hooks.php kronolith => hooks.php turba => attributes.php turba => backends.php turba => hooks.php mnemo => hooks.php trean => hooks.php passwd => hooks.php it is the same, except the app-less line is missing and no error occurs.

Where did you see that you need to create a *.local.php version of the hooks file? I anticipated this pattern from other places to prevent updates from overwriting my changes. Understandable, though the header of the hooks file explains differently since this doesn't work with files that contain class declarations. This file declares the Horde_Hooks class, therefore cannot be loaded more than once. All hooks need to be created in the hooks.php file. I don't have a hooks.php file, only the hooks.local.php. I moved hooks.local.php to hooks.php with the same result. It doesn't make the error disappear. Horde is distributed with a hooks.php.dist file that needs to be moved to hooks.php if any hooks need to be defined. If you are still getting this error, you must still have another file being loaded that contains the Horde_Hooks class declaration (or for some reason you have it multiple times in your own file).
