I removed the sun-java6-plugin package, thinking it was the source of the problem, but I continued to see random theme changes. Then I stopped using Gnome-Do/Docky and went back to using the regular Gnome panel. Since then, I haven't seen any random theme changes. My new plan is to begin using Gnome-Do/Docky again to try and recreate the bug.
If successful, then I think the bug can be safely narrowed down to the Gnome-Do/Docky package.
