You could argue that's correct and desired behaviour - if you have set
serialiser: "JSON", you are, presumably, writing an API, which will be
used by API consumers expecting JSON.  Suddenly dumping a HTML error
page at them instead of the JSON they were expecting would be silly and
wrong - returning JSON describing the error seems much more sane.

So, I wouldn't say it breaks the error page, I'd say it's logical

If you don't want it, though, you could probably get round it with
Yanick's suggestion of using before_serializer.
