Thanks for reconfirming. I now believe (and have updated upstream) that the cause was a 'XKBOPTIONS="compose:lwin"' entry in the '/etc/default/keyboard' file. Removing the XKBOPTIONS line produces the results I expected: disabling the compose key takes effect within both the current session and subsequent GNOME login sessions. I'll continue to investigate the cause; it is OK to close this bug if you like.
