The traces were longer but also so much less helpful for finding the problem than stack traces in other languages, including pure Java. The one I remember getting irrationally angry over how much of a pain it was to track down the bug was where I mistakenly tried to call inc on a string. This was in 2012, I suspect (and hope) it's better now, but later I got more serious about Common Lisp and never looked back (except for occasional thoughts about taking a Clojure job). CL debugging is rather a joy because of its condition system and full live development support that Clojure emulates. (There's also compile-time warnings that tell you about things like incf on a symbol whose derived (or declared) type is not a number.)
