cannot start gnome-panel anymore

[petru.marginean]

Hi,

Suddenly I cannot start the ''gnome-panel'' (when I login or manually)
I get this error when doing it manually:

$> gnome-panel
//...
gnome-panel: symbol lookup error: /usr/lib/gnome-panel/4.0/libwnck-applet.so: undefined symbol: wnck_tasklist_set_orientation

That libwnck-applet.so library misses a reference indeed:

$> ldd -r /usr/lib/gnome-panel/4.0/libwnck-applet.so >/dev/null
undefined symbol: wnck_tasklist_set_orientation    (/usr/lib/gnome-panel/4.0/libwnck-applet.so)

Tried rebooting, reinstalling ''gnome-panel'', and finally I completely remove the lib.
After that I was able to start ''gnome-panel'', but some of the widgets failed to load.

The most I miss "Window List":

The panel encountered a problem while loading "WnckletFactory::WindowListApplet".

Please help,
PM

Sounds like a disk is going bad. What is the SMART status of the drive?

sudo apt-get install smartmontools
sudo smartctl -a /dev/sda

Solved by upgrading to 13.04.
