misc/171078: X and XFCE (xfsettingsd) errors on shutdown/logout

[J B]

I have done some additional testing.
1. I recompiled all installed XFCE ports.
2. I nuked
~/.config/xfce*
~/.cache/sessions/
3. Then I tested as below:

a) $ startx
    I did not do anything, just Log Out from XFCE (orginal
/unconfigured desktop).
    $ cat .startx.log
xauth:  file /home/jb/.serverauth.1817 does not exist

b) $ startx
    This time I configured the desktop (Menu - Settings):
    - just changed some font sizes
    - removed bottom panel, moved upper panel to bottom
    - I did NOT touch Session and Startup (this is where xfsettingsd resides)
    Then I just did Log Out from XFCE (configured desktop).
    $ cat .startx.log

NOTE: lack of this message I can not explain:
xauth:  file /home/jb/.serverauth.1907 does not exist

NOTE:
-  these messages are not present any more
(xfdesktop:1960): GLib-GIO-CRITICAL **: g_file_get_path: assertion
`G_IS_FILE (file)' failed
- xfsettingsd error messages appeared for the first time

After that the .startx.log will look like the last one shown here,
except there will be a random
occurance of two different xfsettingsd error messages (sometimes none).

Do you see anything valuable here for debugging ?
