Preupgrade b0rk Compiz on my laptop.

[Joe Zeff]

Yesterday, I used preupgrade on my laptop to go from F14 to F16.  When 
it was done, I logged back in under XFCE and found that I didn't have a 
window manager running.  I've gotten xfwm4 working on it, now, but I'd 
like to get Compiz-fusion back.  I've tried creating and using a 
different user, with the same results: fusion-icon won't run.  I've 
found this in ~/.xsession-errors more than once from my main login, but 
not the secondary:

fusion-icon: error: option -s: invalid integer value: 'ession'

Also, If I run

fusion-icon -v & in a terminal, I get this:

[joe at barrayar Documents]$ * Detected Session: xfce

...and when I press Enter, I'm notified of a Segmentation Fault in 
fusion-icon.  I've not done anything, yet, on my desktop, as I'd like to 
know what to do if/when it happens again.  I've asked about this on both 
the Fedora and XFCE forums, but haven't had a response as yet.  Anybody 
know what's going on?
