Panel/Orbit Segfault

[Gleef <gleef capital net>]

Panel now is segfaulting on startup.  I am on a RedHat 5.1 system, with
egcs and the glibc-2.0.7-29 RPM.  This is with glib and gtk+ versions
1.1.11, ORBit FOR_PANEL from anonymous CVS yesterday and today, and
gnome-libs and gnome_core GNOME_STABLE from yesterday.

Here's the errors/debug session:

$ panel

** ERROR **: Unknown error on directory creation of /tmp/orbit-gleef

Aborted (core dumped)

Looks like whatever orb.c counts on to set EEXIST isn't doing so with
glibc 2.0.7.
