A problem?

Hello everyone,

Today I upgraded slime using "git clone 
https://github.com/slime/slime.git" after I upgraded sbcl from version 
1.1.17 to version 1.1.18. Slime completed the test suite without errors 
with emacs-23.4.1.

When I do ALT-x slime in emacs, a *sldb sbcl/1* window opens with the 
following:
Interrupt thread failed: thread #<THREAD "Swank 40905" FINISHED values: 
NIL {100343B723}> has exited.
    [Condition of type SB-THREAD:INTERRUPT-THREAD-ERROR]

Restarts:
  0: [ABORT] Abort thread (#<THREAD "Swank Sentinel" RUNNING {100343B343}>)

Backtrace:
   0: (SB-THREAD:INTERRUPT-THREAD #<SB-THREAD:THREAD "Swank 40905" 
FINISHED values: NIL {100343B723}> #<FUNCTION (LAMBDA NIL :IN

   5: ((FLET #:WITHOUT-INTERRUPTS-BODY-660 :IN SB-THREAD::CALL-WITH-MUTEX))

   8: ("foreign function: call_into_lisp")
   9: ("foreign function: new_thread_trampoline")

If I choose abort, it closes the sldb window and leaves me with a 
running repl, but I'm uncertain everything is OK.

Don't really know what to do next.

Thanks for any pointers,

Paul Bowyer
