How to remove gnome-panel-data? Resolved.

[Art Edwards <edwardsa@afrl.kirtland.af.mil>]

I have retrieved my system from the edge of reinstallation. 
scrollkeeper was generating segfault and removing it didn't help.
However, old email showed that libxml could make scrollkeeper 
segfault. I had a repository (debian-unofficial.org) that I'm guessing
had mixed testing and stable together. After removing scrollkeeper and 
retrieving the true libxml2/stable and many dependencies, including 
scrollkeeper, I was able to downgrade everything to stable, where
gnome/metacity has, to my mind, much better behavior.
