@jpangamarca, The first attempt to get a backtrace did not work well. Gnome-panel has a very long list of dependencies though, and I only installed the debug symbols for gnome-panel itself. The effect that I got was that when the problem occurred the gnome debugger seemed to make the problem worse as none of my previously documented tricks for regaining control of the X session would work. I had to use the run application dialog to run killall gnome-panel. There was nothing in the backtrace after the initial startup messages (one for each dependency!) and it noting when I terminated it. The problem occurred when I was using an xpra session to an instance of thunderbird running under another user account on the same machine. There were some xsession messages, which are attached.
