AFAICS this assertion is new as of commit c7f25feb3862. Peter?
I find it rather odd that you're running a production instance compiled
with assertions enabled, though. They have a considerable impact on
performance, and should be used for development or testing only, not
production. I would recommend to recompile with assertions disabled.
Also, it might well be that the assertion is buggy, and that nothing
would go wrong if that assertion is removed and just let the `if` test
below handle the case.
