I'm guessing it is related to the 'trim-end function...
...
    (defun trim-end (string)
      (cond
       ((string= (aref string (- (length string) 3)) 37)
	(substring string 0 (- (length string) 4)))
       (string
	(substring string 0 (- (length string) 1)))))
...

as i think that is the only function that could produce a negative 
number as the argument, if the length of the string were 2 or less.
It might be that a record in one of your .desktop files is incorrect(?),

try the following if you can start sawfish with a custom menu, or by 
setting 'use-fdo-menu to nil, using the latest sawfish from git:

- open your sawfish-client
- enter:
	(require 'sawfish.wm.ext.fdo-menu)
- enter:
	(update-saw-menu)
- [check the apps-menu, just in case :)] - it should be blank if 
(update-saw-menu) failed
- enter:
	*loc-menu*
-- This should output a list of the .desktop entries in order of them 
being generated.
-- Check the last entry
-- The failure would have occured at the entry after the last one 
displayed in *loc-menu*, which will not be displayed.
- enter:
	(directory-files "/usr/share/applications") ; or whichever directory 
you are using for .desktop files
- Find the entry that comes after the last entry in *loc-menu*.  That 
should be your offending file.

If all that works, could you post the .desktop file that gets a failure?

Thanks.
