I'm trying to use cl-xmpp wich uses cxml. I believe there may be an issue within cxml.

The problem arises results from this call:

(defvar connection (xmpp:connect :hostname "jabber.org"))

This appears to be an issue only on cmucl. I'm using version 19b.

Here is the backtrace:

Argument Y is not a NUMBER: #\s. [Condition of type SIMPLE-TYPE-ERROR]

Restarts: 0: [ABORT] Abort handling SLIME request. 1: [ABORT] Return to Top-Level.
