Bug#742807: some changes in the gnome-panel and then back to same behavior.

[shirish शिरीष]

Hi all,
I again had issues after a reboot. This time didn't get any
panel/object in either the top gnome-panel or the bottom-panel.

Running gnome-panel --replace via gdb also didn't get/fetch anything except :-

$ gdb gnome-panel

Do you need "set solib-search-path" or "set sysroot"?

If somebody can share how to set 'the breakpoint' at whichever place
it wants, maybe we get more clues.

Looking forward to know how.
