Comment 6 for bug 36235

I also had these postings for bug #21064
which involved adding an application to gnome-panel.

---------------------------------------------------
I was able to reliably get a similar crash with Ubuntu 5.10
I have the package edubuntu installed (if this makes any difference)
This is on an AMD Sempron 2200 machine.

To get the gnome-panel to crash:

1. Create a new user acount
2. Login to this new acount (from the Ubuntu gdm display manager)
3. Add an application to the gnome-panel (I added tuxpaint)

   Applications > Graphics > Tux_Paint (right-click, Add this to launcher panel)

4. Then immediately resize the launcher panel

   Right-click the launcher panel > Properties > then repeatedly click the
little up arrow to make the panel bigger

   On about the 2nd, 3rd click the panel crashes. The panel starts blinking and
then disappears.
   Even if you re-login the problem remains. You have no panel showing.

   If you do a [crtl][alt][backspace] to leave this now crippled session
   the gdm login screen does NOT return. There is "gdm" process running somewhere.
   To get the login screen back you have to kill the running gdm and restart it.

   The crash seems to scramble a setting somewhere in the .gnome2 directory.
   If you completely erase ~/.gnome2 and let the system rebuild it for you
   then the account is useable again.
---------------------------------------------------

Also....

I was also able to crash gnome-panel if I

1. Resized the launcher panel bigger
2. then immediately added an application to the launcher panel
   (this also happened to be TuxPaint).
