The error left cscope in a failed-config state (although it worked fine for my purposes), and a subsequent update to an unrelated package produced the same error message. I didn't want to get in the habit of ignoring errors from the Update Manager, so I looked for a way to get cscope fully installed. Since I don't normally use the bundled XEmacs, I removed the xemacs21 packages (and gnuserv). dpkg now lists cscope as fully installed, and a subsequent update with the Update Manager completed without errors.
