"cache lookup failed" certainly smells like a server internal error,
but we'd have heard about it if the trivial case you show could reach
such a problem. I'm thinking there's things you haven't told us.
What extensions do you have installed? Maybe an event trigger?
Also, the reference to ENCODING 'ISO-8859-1' makes me wonder what
encoding conversion is being performed.
