Are you using the weather plugin from goodies?  If so, try 
starting starting the panel from an xterm with the following line:
   G_SLICE=always-mallac xfce4-panel &

If it doesn't segfault, then export that environment variable in 
one of your shell init files (I use ~/.bash_profile).

 From what I understand (which may be at least partially 
incorrect), this is a bug in the weather plugin (for 4.2.x) which 
was exposed by malloc changes to glibc/glib.  I *think* it's 
fixed in upstream sources for xfce 4.4 goodies svn repo...
