Brian, can you verify if uninstalling nautilus-dropbox fixes the problem? And if reinstalling it triggers it again?
If removing nautilus-dropbox doesn't fix the problem, try the same with nautilus-share.
It would be great if you could provide a gdb backtrace, see https://wiki.ubuntu.com/Backtrace to learn how to create a backtrace.
