Trying this with latest LO master (on Fedora 16, not Mac OS X, but that 
should hardly make a difference here I'd assume), it does work fine for 
me (and correctly saves the new UserPaths value in 
registrymodifications.xcu).  However, I had to make two changes to the 
Python script (attached):

* desktop and config need to be obtained via the remote service manager, 
not the local one.  (The behaviour of S.createInstanceWithContext(D, C) 
apparently changed with my recent rewrite of the default service 
manager.  Now, D is always instantiated relative to S, regardless of the 
given C -- the latter is only passed on to the instantiated service.  In 
the past, it appears that D was instantiated relative to C's service 
manager instead of the given S -- which looks kinda broken, given you 
explicitly ask S to create an instance.)  Surely a gotcha to watch out 

* If the AutoText UserPaths property does not yet have a value, reading 
its value returns None instead of () (as the property is implicitly 
nillable).  That makes "autotext_path.UserPaths + (path,)" fail.
