I've got two machines with similar GNOME installations on it.  One works
fine the other has had the exact panel/appplet problems Michael Bruce is
describing for over a week now.  The difference is my machine with the
panel problems doesn't even have esound built (no sound card), so the
problem certainly isn't with esound.  The problems hit me at the same time
as gettext became a requirement, but I have no evidence that that was the
problem.

I keep doing complete wipes, fresh anoncvs checkouts/recompile/reinstalls
of (in order) glib, gtk+, ORBit, gnome-libs and gnome-core, in the hopes
that something got fixed somewhere.  If there is something more I should
be updating, please let me know.  Here is some more information on the
problem, note that the applet I am using in all the tests below is the
fish_applet.

* If I run the applet from panel, panel freezes as he described.  If I
  kill the appplet's process panel starts working again.

* If I am running panel, and run the applet from the command line, the
  panel does not freeze, and the applet just hangs (no error messages,
  no segfault, nothing).  Running ps shows the applet as sleeping with
  no CPU time used.  The applet responds to control-C normally.  This
  happens both if I run the applet with no arguments and also if I run it
  with the same "--activate-goad-server fish_applet" argument that
  panel uses.

* If I run gdb on fish_applet, and interrupt it after a while, I get
  the following gdb (v4.17) sessions:

  (gdb) set args --activate-goad-server fish_applet
  (gdb) run
  Starting program: /opt/gnome/bin/fish_applet --activate-goad-server
  fish_applet

  Both of these traces are consistant, that is if I set the arguments
  and wait, I always get the first one.  If I don't, I always get the
  second one.  I have no idea on how to do a trace on the situation
  where panel runs the applet, if someone can tell me, I'll gladly
  send in that trace.

Hopefully this might make it easier to isolate the problem.  Thank you
very much.
