Thanks for your report. Unfortunately we (gnome-panel maintainers) no
longer support Ubuntu 12.04, do you get the same bug with 14.04 LTS?

Title:
gnome-panel crash
Status in “gnome-panel” package in Ubuntu:
Incomplete
Bug description:
gnome-panel crashes infrequently (about every 2 weeks) for one user.
This user has 4 panels, one with the menus and clock, one with the
window switcher, one with launchers, and one with the virtual desktop
switcher. After the crash, logging out or rebooting, then logging back
in results in gnome-panel settings reverted to defaults. The user must
recreate his 4 panel configuration.
I have scoured the web for anyone else with this issue, but have found
nothing. It may be important to note that the user's home directory is
on a mounted NFS share.
/var/log/syslog shows the following:
