I've narrowed it down to the .config/xfce4/panel/tasklist-3.rc file.
Even more specifically, I can reproduce it via the properties dialog
of the Task List by unchecking "Show handle" (show_handles=false in
the config file) and selecting the "Always group tasks" setting
(grouping=2).  As soon as these are set and all windows are closed,
the panel flickers and disappears, and the error I mentioned above is
repeated many times in syslog.  This occurs even with a fresh user.

If I run "xfce4-panel &> panel.log &", panel.log is left empty.


HTH,
Gabriel
