[racket-dev] wrong line marked as source of error?

I think this is probably due to a fairly fundamental problem in the
way that Racket builds stacks. The whole process is pretty complex,
but at a high-level, there are two ways that stack information is
obtained: one way (via the errortrace library) is very accurate when
it exists, but it does not always exist (specifically, the regions of
the stack that correspond to code in the distribution's collects
directory are missing from the stack); the other way is via a much
less precise mechanism, but is always available. I believe that your
screenshot shows you using the former way and so you're missing the
part of the stacktrace that is inside the set-admin method.
