This will work, but catch-all rescue blocks like that can be
dangerous, as they can mask user interrupts, missing method errors,
etc. Using the most specific exception class that still covers the
errors you expect to see in a block means that unexpected errors will
be thrown up to higher levels on the stack, which is exactly what
should happen.
