saveplace problem on Mac OS X

[local]

Greetings,

	I've been running saveplace using development versions of Emacs for a 
while now.  I updated to the CVS Head version recently, and now 
saveplace causes an error on when I try to quit emacs and I have to 
kill emacs to exit.  The error I get is:

Wrong type argument: listp, \.\.\.

Any clues would be appreciated.

        Thanks,

        Gabriel
