Christopher, can you tell me how you found these error messages? I'm
interested in troubleshooting to see if I'm having the same issue.

All I can find is the following in /var/log/messages after I click
"Activities", "Show Applications":

Apr 24 13:56:34 localhost gnome-session-binary[857]: WARNING:
Application 'org.gnome.Shell.desktop' killed by signal 6

Ben
