GAH! So it does! Thats horrid!

The fix is:

diff --git a/gschem/scheme/gschem.scm b/gschem/scheme/gschem.scm
index 748f0cb..42e28cd 100644
--- a/gschem/scheme/gschem.scm

 ; no action hotkey
 (define no-action
   (lambda ()
-      nil 
+    #f
   )
 )


Could this be a guile 1.8 change? I read somewhere that "nil" should not
be used, and depending on context, either #f or () was appropriate.

We should fix all other cases if there are any.

I've not time to commit this right now, so if anyone else wants to, go
right ahead - with a suitable changelog.

I guess this warrants a bug-fix release!
