I just switched from gnome-panel-2.26.2 down to 2.26.1 and the panel starts just fine.

Looks like this is only appearing in Gentoo. Gentoo bug report: http://bugs.gentoo.org/show_bug.cgi?id=272012

Check for a NULL GConfEntry before calling functions on it

The patch attached to comment #8 works for me.  Thanks!

IMO the patch seems to target the "wrong end". I can cause a very similar crash
launching gnome-network-properties (this time in gconf_entry_unref, not in
gconf_entry_get_value).

+ Trace 215902

So it looks to me that we should fix gconf instead.

> So it looks to me that we should fix gconf instead.

GConf is behaving itself here and aborting on bad input — gconf_entry_get_value and gconf_entry_unref both have "g_return_val_if_fail (entry != NULL, NULL);" at the top. The problem is in gnome-panel (and gnome-network-properties).
