Someone deleted ~/.cache or ~/.config/xfce4 or some file in there.
Could also be a bug, used to have issues with Xfwm4 not starting always.
Xfce uses startxfce4 instead of startx, that could account for not
getting everything to start right again. Once you kick the dekstop in,
it doesn't care how it got there, but if done wrong it will lose its
mind and configuration data. You can add workspaces again, from
settings -> Workspaces. They will be empty, but at least they will be
there.
I keep xfce4-panel in startup and sessions, auto-start, just to make
sure it always runs. For reasons unknown, it will sometimes fail to
start.
