Never mind. It probably had to do with something in the cache.

I tried clearing the cache through 'horde-clear-cache' before, but  
that resulted in the same kind of error message. After writing the  
above message, I did a last-ditch attempt to fix this by 'TRUNCATE  
TABLE horde_cache' in MySQL an lo-and-behold, this fixed the problems.

So indeed there must have been something in the cache that prevented  
Horde from running properly. Too bad that also prevented  
'horde-clear-cache' from doing its job.
