I was trying to start up a newly-pulled (from git) slime, and it crashed on both SBCL and ACL.

The problem was that the slime-arglists contrib was trying to initialize itself before swank-repl was loaded, and it was calling swank:create-repl.

When I added (swank-require :swank-repl) to the head of swank-arglists.lisp, that fixed the problem.

Cheers, r
