When running the panel for the first time, it queries /proc/apm to see if the computer is equipped with a battery. It then starts the battery applet automatically. However, on some machines (Dell Inspiron 5000e) this causes the kernel to oops which of course crashes the panel. gnome-session then restarts the panel again, the panel crashes, and gnome-session restarts it again etc. There is a fix for this in latest gnome-core/panel so the version of gnome- core could be patched. See CVS gnome-core/panel/session.c for more details...
