Xfce4 Crash: Need Help Quickly

[Rich Shepard]

   When I logged on my main server/workstation this morning, and entered
'startx' (the alias for startxfce4), the display would not come up. Somehow
it was really trashed overnight (and, no, I wasn't rooted). I've been
restoring from Friday night's backup tape, but have hit a barrier.

   Xfce comes up _very_ slowly. Two of my former desktop contents appear (but
without the xfwm frames, the panel has no virtual desktops, then the pane
disappears. When I try running xfce4panel, nothing happens.

   After manually shutting down X (ctrl-alt-backspace), I see these messages
on the screen:

xfwm4: symbol lookup error: /usr/lib/libpango-1.0.so.0: undefined symbol:

the application.

   This is, of course, a major inconvenience on a work day. I'd really
appreciate your guidance in restoring xfce4-4.2.3.2, the panel, all
workspaces, and xfwm4 as quickly as possible.

TIA,

Rich
