Truthfully, I'm not sure I've ever had one.

The only real error I ever get from Ruby is when I attempt
to call 'foo' on object nil.  ;)

It's sort of an "edge case" thing. Like in Java, the
"pointerless" language, where the most common runtime
error is "null pointer exception."

Of course, probably some percentage of those nils were
from out-of-bound array accesses.
