Looks like xfce4-notifyd seems to be crashing for some reason:

[darose at darosedm ~]$ ps ax | grep notify
  3168 pts/1    S+     0:00 grep notify
[darose at darosedm ~]$ systemctl --user start xfce4-notifyd.service
[darose at darosedm ~]$ ps ax | grep notify
  3173 ?        Ssl    0:00 /usr/lib/xfce4/notifyd/xfce4-notifyd
  3179 pts/1    S+     0:00 grep notify

[darose at darosedm ~]$ ps ax | grep notify
  3511 pts/1    S+     0:00 grep notify

Anyone have any idea what's happening - or how to debug?  I don't see 
anything in the messages.log.

Thanks,
