This fix made my Snow Leopard stable. Now it is snow lovely!
Anyone that’s getting crashes whenever the system tries to save or open docs should try this:1. Start by opening System Preferences
2. Select ‘Sharing’ from the Internet & Wireless section
3. From the list on the left choose ‘File Sharing’ and turn it off.
4. Delete anything listed in the Shared Folders section
5. Turn File Sharing back on
6. Log out, then Log back in
7. Done!!
