[slime-devel] v-iew source in backtrace not working?

In the debugger/backtrace, hitting 'v' on a line usually goes to the source code and brackets the form in question in highlighted blocks. Assuming the debug settings were correct during compilation. But I keep getting this now: error in process filter: Symbol's value as variable is void: paren-mode I checked the ChangeLog for paren-mode, and didn't find it. Is this a new setting I forgot to add? I'm running SBCL 0.9.18 on OSX-Intel and CVS Slime, of course. Jonathon McKitrick -- My other computer is your Windows box.
