[slime-devel] SBCL 0.8.18 with SLIME

I'm new to SLIME. Installing with the latest SBCL seems to go ok with the "Meta-x slime" until I get the following Connected. Hack and be merry! error in process filter: slime-process-available-input: Wrong type argument: listp, \223 error in process filter: Wrong type argument: listp, \223 Can anyone suggest how to deal with this? Thanks
