Suddenly applies for all filters there, not just for those containing an umlaut or regex. Error occurs not always, but in, let's say, 9 of 10 attempts.

Looks like a schema change has slipped through the cracks here. Could this be related to Tim's running schema changes earlier today?

I've looked at the error logs and I can find the error on alswiki, from lots and lots of different servers.

It's a bit strange, the code isn't supposed to be updated on those servers.

The same problem occurs on nl-wikipedia. We cannot commit any changes to filters.

Did a live hack on Wikimedia to fix. I suggest implementing a permanent fix along the lines of using an explicit field list for any INSERT queries instead of trusting the DB. Also you shouldn't be selecting data from a slave and then saving it back to the master, that could lead to some nasty unintended reversions if there's any replication lag.

I've sorted this out in r52048.
