Hi,

I took the updates after running "apt-get dist-upgrade" command in
terminal after applying the updates. I was not able to view dock. So i
exited from dock during exiting dock was crashed.

"Is it possible that now the icon is removed or partially unref'ed and

well, the dock destroys the icons that belongs to a dock when this one is
destroyed.
so it's possible that the icons created by the applet are already destroyed
before
actually, it's quite possible since this applet is a plug-in (= has no
icon, so no link to a dock).
a solution is to register to the "destroy" notification on the icons
created by the applet, and when the callback is called, remove it from its
internal list of icons.
(of course, the applet should take care of it when destroying the icons
itself, for instance by removing it from the list before unrefing it).
