SLIME breaks pretty badly post [svn r12306] leading to the following 
exception:

The backtrace function seems pretty borked as well, in this non-SLIME 
test case:

I'm on the go for the next couple days, so I don't have a whole lot of 
time to help track this down, but I wanted to give Erik a head's up.
