Situation
Exception in
ZenTrayIcon when zmd Starts on SLED 10
Unable to
get SLED 10 updates
ZEN Updater
does not stay loaded in the notification area
ERROR:"System.NullReferenceException:

Resolution
The cause
was due to undocking the SLED 10 laptop from the docking station
while the laptop was powered on that appeared to cause corruption of the zmd
dabase file (/var/lib/zmd/zmd.db).
To resolve
the problem, delete the zmd.db file by logging in as root
and from a command prompt type:
cd
/var/lib/zmd
rm
zmd.db
After a
reboot, zmd should load properly and obtain the necessary
updates.
