Autocomplete on "clojure." causes debugger to pop up [fix included]

[MHOOO]

The debugger constantly pops up when I try to autocomplete a namespace using swank. I can easily fix this though by compiling the following (in any file):

;;; FIX FOR SWANK on clojure 1.3
(in-ns 'swank.commands.basic)
(defn- maybe-resolve-sym [symbol-name]
  (try
     (let [mns (maybe-ns *current-package*)
           sym (symbol symbol-name)]
      (ns-resolve mns sym))
    (catch ClassNotFoundException e nil)
    ;; for some reason we get back a RuntimeException...
    (catch RuntimeException e nil)))

This happens only when using clojure 1.3 - mainly because the ns-resolve call throws a RuntimeException with a cause, instead of directly a ClassNotFoundException. I'm using swank-clojure-1.4.0

I'm curious what is the RuntimeException being thrown and which debugger is popping up (sldb or the emacs lisp debugger)? I'm not seeing this on 1.2 or 1.3.

SLDB is popping up with the following content:
